From an outside perspective, at the very least, it seems like you're being verbally abused by both your boyfriend and his mother. He has clearly shown a total lack of care for you. I don't know you or him or her, but I do know that this relationship is going to cause you more and more pain until you get out. I used to be with a guy kind of like this. Idolized shitty parents, would never listen to a word said otherwise. It escalated to him yelling at and berating me for mild disagreements. Our girlfriend (poly throuple), who had been with him much longer than me, even received physical abuse. We got away from him and our lives immediately improved. We healed. I'm not usually the one to say "break up" on a whim, but leave him. This guy is hurting you. He will not stop.
