The good news is this seems to be going well. Your H may come around, and if things do get worse he'll have a hard time rewriting history with you demonstrating those changes and having this kind of fun together.
It IS really hard, particularly because this could last a long time. It could get worse. It could last a long time, seem to get better, then he could BD again in a year and actually move out. And living in Limbo WITH the person is so tough. I never really had to, but I can't imagine.
I would remind you to work just as much (if not more) on detachment and GAL as you are on your 180s. You're only 3 months in and early in the evolution of your sitch. I know you're still raw and scared. Please take care of yourself and start putting yourself in a place where you will be ok regardless of the outcome. I don't just mean he stays or leaves...would it be possible to get detached to the point that you don't even care if you stay in limbo for a few years? Think how powerful that would feel. Keep trucking!
