I don't know that I have any insight to this conversation, other than to say whatever happened before you two were together is none of your business. You got into the relationship knowing that she wasn't a virgin so you have nothing to complain about. Were it something revealed to you on your honeymoon, well, I'd immediately get an annulment; but it was disclosed and you continued to persue the relationship after being told.
Do I endorse pre-marital sex? No, not necessarily. But I do understand that everyone has been in circumstances in which I have no insight. The fact that she currently holds a Temple recommend says that she's been forgiven by the Lord; and unless you're suddenly a higher authority than the Almighty, you have nothing to say in this matter. Nothing at all.
I've done things in my life I'm not particularily proud of; is it your right to be angry with me about them?
"I, the Lord, will forgive whom I will forgive, but of you it is required to forgive all men." D&C 64 - 9
True repentance = True forgiveness; in other words the sin never happened.
