Sounds like some really good reasons to me, NOT!
He says he wants to stay married because you'll never trust him again?? yeah, seems like a good reason to me. Is he doing anything to try to earn your trust back?
Yeah, he has done some shitty stuff (if your here I am assuming he has, I haven't read your story) At least he admits that, but what is he doing to make it up to you?
What really gets me is I don't hear any "I love you" in there. Sounds like pure laziness. You know what he is, he doesn't want to have to put on an act for someone else.
Ok, so I am not in the best of moods tonight. Nothing to do with Dh, but I probably should just keep my mouth shut and sit in the corner.
