Hello twinkle, this sounds exactly like my XABF, to the nail. I'm so sorry he acted like a jerk and abandoned you when you were in pain and needed help the most, I know that situation well.
I would keep a lot of distance between you two now and wait to meet with him until he has at least a few sessions with a therapist down.
Men like this will say anything to get you back, and then the trouble and chaos starts all over again. It is a vicious cycle. Just focus on you, you, you right now.
I hope this helps. And above all, thank you for coming here!
