I actually don't try anymore so the self doubt and confidence aren't problems for me. I'm holding firm that if he didn't want to be with me he'd break up with me, otherwise I'd go crazier. As far as bitterness and resentment it's there, but we've talked and I believe him when he tells me it's an issue that he's having, so most of the time when I feel bad about it, I just feel sad because he feels so bad about it. You're correct that every month it gets just a little worse, and it'll just keep getting harder to fix. It's like gaining weight. It starts slowly and then years later you realize you're super fat.
