Hi Alura,
Welcome to PC!
In my opinion, this is definitely emotional abuse. This guy sounds like he has major, I mean MAJOR issues, that have nothing to do with you. I think you would be doing the right thing if you distanced yourself from him as much as you possibly can.
I was in an emotionally abusive relationship once, only the guy I was with was bi-polar and used to self medicate himself with drugs and alcohol. He would be nice and sweet one minute, and raging and abusive the next. It took me a long time to realize that he had severe problems, and I ran (not walked) away from that relationship. It was a long time ago, and I am so glad it's over.
I don't think you should put any blame on yourself at all. I do think it would be much healthier for you to move on. (Also him trying to make you feel guilty for any reason, or comparing you to other girls by telling you about them, well that's just his way of trying to manipulate you.)
Please do yourself a favor and move on for good. It's good that you're in therapy, and it would be even better if you can move away from this relationship and put it behind you before it gets worse. No one should be subjected to any kind of abuse, you don't deserve to be treated this way. Please take this into consideration. (Just my view on things, from an outsider's standpoint.)
