BobbiJo, First let me apologize for not being there when H dumped that bucket of $hit on you. I was too wrapped up in D's sk8ing and that stupid blizzard that hit us. I had such a hard time online yesterday because of the weather and I gave up. Here are my thoughts....
1. Seems H has finally laid it all out for you. He finally realizes and admits that he is sick. He needs help and hopefully he will start that IC soon. My H finally told me this past week that he needs to work on himself first. Your H really needs to focus on him now. As messed up as he is you can't work on the R now.
2. I understand you having a hard time believing it is over w/ the OW. I have told H that I don't feel I matter as long as EAs are around. H tells me that is not true, but I think it is BS. You will just have to sit back and see if it is really over.
3. I think you need to do like Kalni did and act if the D has already happened. Only talk to H when it is about the kids. If he calls you and wants to chat about work I think that is ok. That is something my H didn't do for a long time and he now does sometimes so I take it as a good sign.
4. I know it sucks, but you need to find somewhere to go when H is there. Let him have time w/ the kids and space from you. I know when our bomb went off H was very uncomfortable being around me w/ the kids. When it is his weekend or night I try to get lost.
