Afa, it seems that you've been getting positive results from some of the things you are doing. I'm glad :-)
What I did that didn't work was signing "with all my love, your wife," and being extremely devoted and loving when he was pulling away from me and being unfaithful. I was also not asking about his whereabouts. I later found out he was with the OW, and he told me that my not asking "helped" him have the affair. I wish I had asked. I guess DB didn't work so well for me last year.
I think my behavior gave him the message that I would tolerate everything he did, and that he could walk all over me and I would still be there. I think that situation hasn't changed much. I'm GALing and not contacting him until he contacts me (it's been a very long five days) but he still thinks I'm just there, waiting for him to change his mind. Anyway, my point is, when someone is involved in an EA or PA, all you can do is better yourself so the other person realizes he's being foolish by leaving you. And wait. Lots of patience. It's tough. I hope I'm helping a bit. Good luck Afa.
