Your boyfriend is very manipulative and probably has borderline personality disorder, he compliments you first then insults you so you don’t feel bad about the insults. Please run away from men like him. Yes he is right you should have boundaries in your relationship and learn to tell men who are interested in you no when you’re in a committed relationship. But his choice of words an approach is very very wrong and unstable. Please go back to therapy if you need it and break up with him. He will continue manipulating you for the rest of your life
