Exactly

Then in that case I would suggest you continue working on the relationship,and put off getting married,until you feel the relationship is back on steady ground.

He waited 8 years to ask you to get married,he can wait until your damn well ready.

Unless you can rebuild the trust completely,you shouldn't marry him- just because now he's finally asked you.
Could you go back for a few more counseling sessions?

Love isn't a game... it's not about giving in, losing a battle, or winning a fight...

It's about trust, communication, and honesty.

Simply by that definition, I'd say that you're not ready to get married... not because you'd "give in," but because you don't trust him, you're not communicating what you're feeling, and honesty isn't on the high priority list.

Stay in counseling, try to work out the problems, but above all, talk about what you're feeling. Nothing is going to be resolved until you are both honest about what's going on.

That is what happened to my ex. He and I were together ten years, he left me and started living with a girl I knew he was cheating on me with. He then cheated on her with me, she found out, and less than two months later he proposes to her. He basically is trying to win her trust by feeding her the marriage card. But there is no trust between them, they are planning a wedding, and will get married, however it is based on the wrong reason. Had he not cheated, he would not have proposed. Is that the case with you also?

Do not go back with him because he is going to do it again. He feels bad now but show him you deserve better and as for your kids talk to them and tell them to forgive him, after all he is their father. But do not go back to him it's going to boost his ego. I tell you from my experience from my last relationship.
