dearme, I just read your entire sitch and I think you're doing really well. You've made a considerable amount of progress in the past few months. (I realize it may not seem that way when you're living it though.)
Anyway, my situation is similar in that I got the bomb in April, and my H and I also continue to live together with affection, cuddling and time spent together alone and as a family. The difference is that my H will commit to the marriage for a couple weeks (or at least seem to), then start withdrawing and then bomb drop again. Then day after a bomb, he will give some indication of wanting the M again.
That said, I learned a lot from reading your thread. You have successfully detached yourself to a greater degree, and I now think I have a clearer picture of what I need to do in my sitch.
I'm sorry I can't offer any advice but I definitely do see some positives in your situation. Continue DB'ing and GAL'ing and hopefully your W will continue to take notice.
