I too am going through something same. I moved out of his place 2 weeks ago, because of abuse and all. He was a very selfish person. But now he just doesn't accept his faults, he keep saying that he took care of me and all, when he didn't. Always fought on money.
Now he and his family is blaming me that I must have found someone that's why I am separating. I also feel doubtful at times, though I know how selfish he was at times, and how abusive he was.
I know how daunting it is when the person who abuses acts like they are the victim.
Pls trust yourself, take care of yourself. Hope everything goes okay.
