He is definitely still bring manipulative.
My ex had a lot in common with your Exp.
When I split up with my exp, it took several attempts. He kept trying to "commit suicide". I ended up in hospital with his a couple of times.
Looking back, he really wasn't trying that hard! Seeing as he had easy access to hard drugs, but he was going for everyday medicines, and not even enough for the hospital to find dangerous levels in him.
I was sucked in at the time though, and it dragged the process of breaking up into months and months - over a year. I knew I didn't want to be with him but he kept wheedling his way back in. I only got away once I met someone else.
Part of the problem is you (and I) are too nice, and he is using that to manipulate you.
His response is not a normal response to a relationship breaking down, but he is not normal. He doesn't think like you or I. He does not care about how he is affecting you (even if he says he does). He wants to own you and control you.
You need to stop worrying about him, or at the very least stop acting on your worries about him. You need to worry about yourself and most importantly your DCs.
The man has chucked you out of your house! You should be fuming!
And a sexual assault is much worse than an affair, can you see that?
You should be at home with your DCs.
You are going to need to stand up to this man.
