Lily, I'm sorry you're in that situation, hopefully you can get some practical advice from the other posters here.

I don't know enough about the kind of arguments you have to see whether it's emotional abuse or whether he's just being unfair in bringing up the past. A lot of arguments feature the deliberate opening of old wounds for some reason. I've done it myself.

In which case you probably need to let him know how his arguments affect you.

But if he's systematically bullying you over your mistakes or your past, then it's emotional abuse isn't it?
