It really does help DR, thank you.
You're right about giving myself time. I think I should look at at least a year. I'm an 'anniversary' person (in the sense of 'this time last year...') and I know from bereavement that it's better after a year. In my head, I'm looking towards our next wedding anniversary. The last one was a month or so after he'd told me about the affair but strangely, it was our best one ever - though this was probably due to the 'hysterical bonding' effect.
And the fact that it was the only one either of us had ever paid any attention to!
I get your second point, I think , about separating then and now.
When it gnaws, I feel several things. Obviously very deeply hurt and betrayed. I also feel sad for the years we lost when we both wanted the same thing ie the kind of thing we have now. Neither of us knew how to ask each other for it as we'd both built walls. I do still feel angry sometimes but not nearly as much as I did at the beginning. I also feel jealous in that I would have liked to have been abroad with no kids to look after and a new person who was interested in me and made me feel special - resentful is probably a better word. I'm fascinated by her in the way most wives are. I'm disappointed in him. I despise what he did but not the whole of him iyswim.
The pity thing, I already do. I would absolutely hate to be him, knowing what pain he's caused to me, the OW and possibly to our children in the future if we split. He is genuinely remorseful and eaten up with guilt. He really does understand what he's done and in no sense tries to minimise it.
The thing is, he would move heaven and earth to turn the clock back if he could, but I'm not so sure if I would. We've learned huge amounts about ourselves and each other. I can't honestly see any other catalyst that would have caused this to happen. We are different people now. I certainly like myself and him a lot more!
What I'm trying to say is that it happenened - can't forget or change that. Ultimately, a lot of good has/could come out of it in one way or another. There is no way I could 'punish' him more than he's punishing himself - even if I wanted to.
Separating then and now, allowing 5 minutes 'dwelling' time and giving myself time seem to be a good way forward.
And obviously, we'll keep talking.
Thanks again Dr
