my two cents

More thoughts:
- Are you the rebound girl? How much time had passed between the end of his engagement and starting to date you? (you don't need to answer just something to think about) Breaking an engagement should take time to heal (esp when sex was involved) but did he think getting serious again was the solution?
- Do Not Settle!
- Read this and send it to him as well: http://middleagedmormonman.com/home/2013/06/romance-and-mission-prep/ then end this relationship so he can focus on his mission and you start dating other guys.

Thank you! That’s a great idea! I know he loves in n out and bowling! I might do that! 

I'm just gonna address this one:  "Who am I to judge?"
You sorely misunderstood this teaching.  We are not to judge a person condemned but We are taught since Primary Sunday School to Choose The Right.  Choosing the Right requires Judgment.  Therefore, no, you can't judge a person as someone fit for the fires of hell but you SHOULD and HAVE TO JUDGE if such a person is good for you to marry.

I basically agree with JAG, and I more or less echo his sentiments, without the bitter edge. I believe that your boyfriend may indeed be a decent, kind person who walked several steps (or maybe half a mile) down a path that he now regrets. I don't necessarily think him an egoist, a manipulator, or a jerk for detailing his sexual past, including how much his former girlfriend pleased him sexually. As JAG suggested, that may just be immaturity, the type where you fail to take into account the feelings of the person you're talking to. Your boyfriend has a great deal of growing up to do, but we may assume that he will probably do just that.
The bottom line is this: You do not owe it to him to marry him. You do not have to prove your non-judgmentalness by marrying him in spite of your feelings of betrayal. YOU ARE ALLOWED TO DECLINE TO MARRY WHOMEVER YOU DECIDE NOT TO MARRY, FOR WHATEVER REASON YOU DEEM SUFFICIENT. Maybe you don't like his haircut or his body odor. Maybe you think he's too short or has too much acne. Maybe you don't like his skin tone, his accent, or how he always says things like, "Me and my buddy went fishing." It does not matter how trivial or stupid your reasons are. YOU get to decide whom you marry and whom you don't marry.
And for the record, sister: Deciding not to marry him because he fornicated before meeting you and he doesn't seem particularly contrite about it does not strike me as either overly judgmental or beyond the pale. If you can legitimately refuse to marry a guy because he's bald or Hispanic or bearded or too tall or green-eyed or left-handed, you can legitimately refuse to marry him because his sexual past doesn't jibe with your own desires or standards.

A “good guy”—well, a marriageable one, anyways— wouldn’t have burdened you this extensively.  I mean, there’s a time and place to say “I’ve had chastity issues”; but one doesn’t get into detail, or show the former partner’s picture to a later partner, or talk about how sexually pleasing the former partner was; unless one is either a woefully clueless little boy, or a smug player trying to mess with your head.  I get a vibe from you that he isn’t all that contrite about what he’s done.
Whether I’m right or wrong about the above, you are not a bad person if you show him the door.  This isn’t anywhere in the same ballpark as “will-I-be-able-to-let-it-go-if-he-bounces-a-check” or “will-I-flip-out-if-he-forgets-to-empty-the-garbage”.  He had sex, in violation of his covenants.  Repeatedly.  And he succeeded in doing that, apparently, in part by making a false promise of marriage to some other girl.  That is a Big Deal.  More power to you, if you can move past it—but a lot of women just can’t; and that’s OK; there’s nothing “childish” about holding out for a husband whose history confirms that he knows how to keep covenants.
Moreover, you can forgive someone without marrying them—and if he suggests otherwise, that just goes to show what a manipulative dirtbag he is.  There’s nothing Christlike about letting some guy guilt you into sharing his bed. 
(Just my two cents.  Welcome to the forum, by the way.)

A gift card to his favorite restaurant or to a place he missed (ie bowling alley) and make a homemade card to put it in. 
Welcome to the forum!

Since you do not know anyone who is religious, and you probably want to get a down-to-earth understanding of the religion you are about to learn of, you might try visiting http://www.mormon.org  The site is an official explanation of the church, specifically for those who are unfamiliar, but interested.  http://www.lds.org is also an official site, with much more in-depth information, should your curiosity make you want to look deeper. 
This site is good for raising questions that regular members of the church can answer. The answers here are not "official," but most posters are knowledgeable. I am not a member, but came here with questions. Despite not converting, I found the people and conversations so friendly and informative, I've stayed around. 

Sorry about your son. That's really sad. I've seen these suggested. Not sure which are for phones and which are for homes.

I'm sorry with how some have responded but I would hope you wouldn't judge an entire religion based on *imperfect* people. After all, that's all this Church has as members.

What about going to both? Even if you don't go to your ward if it's at the same time as his church, you can just go to another ward instead. Hopefully your husband will see this as a reasonable compromise.

I was talking to a missionary who said polygamy shook her faith horribly when she first started her mission.  I didn't ask details, but I assume it was something an anti hit her with.  She worked through it.  I'm often surprised what people in the church don't know about their own history.  Maybe it's just because I've been researching so much.  
That said, why would it be something regularly talked or spoken about?  I mean, it's certainly not hidden, but I don't know why it would be taught unless just to prepare people for the accusations.  It has nothing to do with the plan for salvation.  It has nothing to do current church doctrine.  
Additionally, why read the 1937 version of The Book of Mormon?   Assuming @Blossom76 accepts modern prophets, it would make sense to read the most current version.  I would put forth that if her husband has a sincere desire to try this, he try it correctly.

A sincere "thank you" doesn't cost anything yet too many can't seem to even manage that. An example - For years, I've wondered why those who get Christmas provided by the ward via an angel tree can't write thank you notes and hang them where the 'I want' tags were. It can still be done anonymously and it would show that they didn't just expect it or feel entitled.

Everyone, let's get off @Blossom76's case.  She's been with us for a while, has proven herself as an honest investigator, and a very fine person.  Yes, those of us on the forum have heard anti-folks play troll / wolf-in-sheep's clothing with this very question 99 times.  But Blossom is NOT such a person.  Let us not turn away the 1 honest seeker just because we've seen 99 trolls.

Since this is Christmas and a season of exchanging gifts – what are some of your thoughts concerning D&C 42:54

My thoughts - Someone on a mission is not always how they are in the 'real world'. I thought there were clues/connections with someone I dated at your age - but I'm not married to him. Lastly, you need to date!! You don't have much to compare this guy to yet nor do you want to look back and wish you had enjoyed the dating scene while you were able.

Elder Bednar speaks to the success of last year's campaign: 
To me, the most significant thing he said was, "Our hope was that people would not simply learn more about the SAviour, but that they would learn about him by doing what he did." This echoes Elder Oaks' sentiment that the gospel is much more than coming to know things...it is about becoming something, and through becoming we fully know.
Thanks, -Wade Englund-
 

The great thing about this program and its associated calendar, is that it forces my enemies to reveal themselves—I know I’d better keep an eye on anyone who does something nice for me on December 8.

I've read these two verses, dozens, possibly hundreds of times but its only just now that I've noticed that Joseph Smith and Mormon were the same age when they first saw Jesus. It always gives me a bit of a buzz when I suddenly gain a new understanding or find a new connection between different verses of scripture. It's happened many times, but it still surprises me, in a nice kind of way, how we can suddenly gain new insights from stuff we've read or heard many times before.
(Book of Mormon | Mormon 1:15)
15  And I, being fifteen years of age and being somewhat of a sober mind, therefore I was visited of the Lord, and tasted and knew of the goodness of Jesus.
 
(Pearl of Great Price | JS-History 1:7)
7  I was at this time in my fifteenth year.  My father's family was proselyted to the Presbyterian faith, and four of them joined that church, namely, my mother, Lucy; my brothers Hyrum and Samuel Harrison; and my sister Sophronia.
 
Does anyone else have an experience about the joys of scripture study they'd like to share?
 

I'm not sure this follows.  There's a very big difference between watching the movie and living the movie.  Especially for a female.
On the flip side, one of the biggest problems with women reading romance novels is that they tend to start to expect to find the guy in real life - or in their husbands.  Imagine your girlfriend/wife yearning for you to be just like the guy in The Notebook.  True story:  a friend of mine broke up with his fiancee because she asked him to read The Notebook before they get married.

I'm so happy right now!
As some of you know my husband is very Catholic and I'm investigating the LDS church, I love the Book Of Mormon and I'm praying to know if its true (nothing yet but I'll keep praying!) but my husband was umm lets just say 'less than impressed' with the whole idea.
Anyway, we have come to a compromise.  If I study the LDS faith for 18 months in depth and still want to join he will be supportive of me and even come to my baptism!  The only condition is that I have to study the Catholic faith at the same time (his point is you can't leave your own church for another if you don't even have a proper grounding in your own faith.  He also thinks I should have a proper understanding of the LDS faith before converting).  
He doesn't mind me attending LDS church as long as I go to Mass with him first (which is fine because the Mass is in the morning and the ward for my area is in the afternoon).  I do try to go to LDS church every week but honestly I need to be more dedicated (4 hours of church a week is a long time!)  
He has also agreed to study the LDS church with me (he will also help me study the Catholic church as well) and read the Book Of Mormon.
God certainly does work in your life if you pray and keep faith.  This is definitely progress people!

Well, instead of the ward angel tree this year I'm considering how to give to those affected by the recent fires and hurricanes - but to each his own.

Agree with what Zil said. I also think part of it is because the boys have courts of honor, etc and this helps close the disparity.
