What do I do now - Just leave him to it & see if he tells me he's cut contact?
I think you do two things....1) what you've been doing, because that's working and 2) GAL! You're life is not on hold...keep working on you, do things that make you happy, make some new friends, call some old ones, etc.
If he comes around, he'll have to realize that trust needs to be rebuilt, and at least in the short term, transparency will likely be needed to help with that. But none of that will happen quickly.....so while you can think on it, there's not really anything "actionable" at this point in time.
