Yikes. You have just described one of my worst case scenarios from when I was married. If she came back what would that look like? Would I be in fear or ?
Seems to be different for many, but I suspect it would have been similar.
I also think it sounds like control and not that he wants to make things better. I suspect alterior motives to those stated by him.
