thank you doctor.may god bless you.
It often happens when people come out of a world where "The people who love me are the people who hurt me."
Don't worry about the origin or nature of the disorder, start by protecting yourself. Don't tolerate abuse. Use avoiding him, separation, legal means, family pressure, whatever it takes to keep from being harmed physically or emotionally.
Don't waste your time asking if it is a disorder if both parties like it--obviously you don't!
Second and only second see about getting therapy, for yourself first, then couples, then him (if he is open to the second two.)
It won't get better on its own, you have to take extreme steps to break the pattern. Don't let shame or intimidation keep you from acting to protect yourself.
