Yes, I believe things are going better with the person on the other thread. Lots of DBers have been very supportive which is great to see. I don't really follow anything in newcomers, I just happened to see that thread that night.
Anyway, how is PM going? Have you read the case about the couple stuck in the asexual marriage and how counterproductive the hands off + space approach is?
I think you were right when you posted on mamabear's thread: your W does not see you as a sexual being. This is likely a long standing problem, compounded by the guilt.
I'm glad to see that you are still managing W's psychic well-being so carefully (sarcasm). I'll be interested to see what happens after the "few weeks" you think it will take W to be OK, given that her psychic fragility has controlled so much of what you do throughout your M.
Maybe she doesn't see you as a sexual being because you parent her too much. This is much different that being a supportive and nurturing romantic P.
To be honest, if I were your W, after having an A with some kind of passion in it, I'd again be seriously looking at leaving at this point and probably making a plan to do so, maybe a few years down the road. You know, do it the "right" way.... But, I doubt I'd have my head in the M very much. Having found myself sexually reawakened and then put back in bed with what feels like a sibling, I'd be unwilling to accept giving up my sexual self for the long haul again.
You are playing half the game here in which you are an asexual bedwarmer. All this does is maintain the status quo. I don't think that is going to get you anywhere.
