She sounds exactly like I did. The fact she does not know what to do now is a good thing. She hasn't totally closed you off.
I think I missed something..what is the 6 on 6 off? You don't want to enable the affair by not being home if that is what you mean by 6 off.
You sound like my h in your forgiveness. It sounds like the validating is good. One thing to mention is that when I was in the midst of the affair, I wanted my h to admit we were not meant to be, that there was no passion, to agree that we shouldn't have gotten married....don't do that. Validate her feelings, but don't agree.
I told my h that I was not attracted to him anymore (even though he was wayyyyy more attracted than the OM). I told my h that I thought we married just because it was the right time in our life, nothing more. I told him that we BOTH (trying to suck him in) deserved happiness and love and that together made me like myself less. I told him that I diddn't have passion and now I don't ever see it coming back.
Don't apologize. We are here to help. We have all been here in some way or another. I'm going to throw something else out there.....Retrouvaille. Google it. It could be just the thing you need to get through to each other and start again. At least something to keep in your pocket. I remember feeling utter hopelessness...and so did my h...Retrouvaille helped us feel like there was hope.
