I didn't have much time to read it all, but.... his THERAPIST?!?! o.O OK now that's crossing some sort of professional boundary, but I suppose it happens. Next question is how was the therapist unaware of his marriage? If she wasn't unaware how would this embarass him?
As for filing - do you want a D or no? I suggest if you want to reconcile DO NOT file, make him do it. As for DBing itself, sounds like you did it already. Detach, GAL, keep making him make the moves, but if there is still a OW make sure you keep your boundaries that you won't be in an open relationship. But I suppose I should sleep some tonight, good luck, ttyl.
