I am terrified that one day y dad is going to get so angry that he beats up my mom. His temper is getting do bad lately and we don’t know who to talk to about this. My mom went to his family and he lied and made all of our problems seem like it was her fault. Now they all shun her. Her family has been supportive but they dont want to get too involved bc it’s not their marriage, I dont know how I will leave her alone when I leave for college. He has hasn’t hit her yet but he has threatened to and then we all pretend like nothing happened the next day. I can’t keep living like this. I am always waiting to see what kind of mood he is in. We never know what will set him off. I constantly feel like I’m walking on eggshells. My mom arranged for them to see a therapist together after she found out he had an affair last year (he stopped going after 2 sessions) and the therapist thinks he has borderline personality disorder but she hasn’t talked enough with him to officially diagnose him. I really want my mom to just give him an ultimatum: either he sees a therapist regularly or they get a divorce. I love my dad. I really do. But he’s not the same person he used to be and it’s killing me. I just want my dad back.
