my 2 cents...from my experience.
I went inactive from church my senior year of high school. i did not return to church til i was 34, in 2000. during that time i had no desire to marry and did a lot of things i shouldn't have.
when i started going back to church i decided i wanted to go to the temple, and get married in the temple. I lived in the desert in southern calif in a ward whose boundaries stretched about 25 miles in a stake whose boundaries were about 40 or more miles.
As i looked around my ward, there was 1 attractive single gal who i thought to be about 24. there was a divorcee with 2 kids in their early teens...she was about 40 or older. that's it!!...and the gal i thought to be 24 turned out to in high school and just 17!!
i moved to utah to better my odds, was there 6 months before moving to wyoming for work. i went on lots of dates with people i met in an lds singles chatroom. most had children. the ages ranged from 25-45. most of the younger ones were too immature, some were divorced with kids. all the older ones were divorced with kids. i remember talking to a gal who told me she had 8 kids!! i was open to one or two, but 8 ??!!!
eventually i did find a gal who was 34, never married and no kids. we have been married for over 6 years. our daughter is 5 1/2 and our son just turned 3.
there is hope!!!
