Thank you everyone, for your responses. I feel less anxious about it now.
lordhasaplan, of course you are right. I'm obviously not ready, or I'd just do it, and not be unsure. I wish I knew why. There certainly are things that bother me more than others, but I don't think I can pick and choose. You and mhcs and Lark all offer the same advice, to try and forgive some aspects. Sometimes it seems like I am trying to forgive him for not being being the person he was supposed to be, for not having character, so while some actions are worse than others, they are all in same bucket of sh#t. I might try and think about this, though.
Sisoon, the EA started in late June 2013 and became physical in mid July. DDay was Sep 20, 2013. it was a little less than 3 months. I def do not trust yet, and he knows and accepts that. Our MC makes me feel as though she thinks I should be moving along, and sometimes I feel pressure to be "better" than I really am. But when I feel like that, I just say so. For the most part she is wonderful. I know without her we would NOT be together. She has not mentioned forgiveness, probably because I haven't.
needfriendshere, I know what you mean. I had to have ALL the details to. I wanted to understand how he could do it. So for weeks after DDay I peppered him with questions, one after another, at all hours of the day and night, and he answered them all. It is a double edges sword, though. first off, I will never "understand" it because I would never do it, and I needed to know ALL the details so that I didn't feel like there were any secrets between them, but of course, once you know, you can't un-know
brkn_hearted and Ausman, I hear that alot, that forgiveness is for me, and not him, but I don't really get that. For me forgiveness means that I believe he is genuinely remorseful, repentant, that he owns what he did and understands the magnitude of it, that he appreciated the gift I've given him by choosing to stay with him, and that he will NEVER do anything like this again.
Cosmicjoke, yes, I think it is alright. People keep saying I have to forgive the OW, and I have no intention of it, never, ever, ever. I am completely at peace with that.
