Relationship advice

My live in boyfriend and I have been fighting nonstop. He will do anything to win and argument. And we argue about everything. It’s gotten to the point even when he’s right I won’t admit it because he never thinks he’s wrong he is never sincere and apologizes. And I mean never believes he’s wrong never. He never admits faults. He’s started to go to all lengths to win. He says things about my kids, my family, my friends the few I have and my colleagues. When that doesn’t work or I start doing the same he’s started blaming me for everything and every fight. He says I’m depressed I need meds, I’m in menopause I need meds, I’m Bipolar, I take my dislike for my boss or my job on him, I am harboring issues from my past and taking them out on him. He’s just protecting me but he’s the one hurting me no one else. . Now yesterday the new one is he’s dying. All because he brought up a subject we had already fought abiyt. Normally I end up doing what ever he wants. He micro manages me like a child but like a child I do what he wants because if he were right and I did r I’d never hear the end of it. So anyway he bri gs up a subject we’ve fought about already and again starts a fight. Now I fight and fight over anything because I can’t stand it anymore being told I’m to blame and Wei g. So we are fighting g. We finally drop it. And he goes through this whole thing how no matter what I’m not to let anyone do is respect me again cut me down again and not tell me I’m amazing from that point forward if he’s not there to never ever let anyone treat me bad. He’s crying I’m crying he says if he dies to promise him. Let me add he fake cries all the time. I ask him why he thinks he’s dying he won’t answer. About 30 minutes later he bri ga up the same subject we fought about hours before that so here we go again fighting. Then he asks me to look up the words perspective perception amd opinion. And we argue about the meanings and though I had look up both perspective and perception he swears I didn’t and we argue about that. I mean how stupid I looked them up he would t beleive me I showed him my web history he did t beleive me and I admirable purposely then disagreed with the meaning’s because he was being such a *** then he says I’m fyi g and your treating me like this. He has a hiatal hernia and won’t get surgery right now because he doesn’t have insurance. So now to win a fight that he started he tried to make me feel guilty. I ask him why he thinks he’s fyi g if a doctor told him he was. He won’t answer because he hasn’t even been to a doctor. I slept upstairs sobbing and crying he didn’t care he won but now I just want to sell the house and be left alone forever. I don’t wan to love sad and feelings like this. I think it was a low dirty move to pretend like he’s dying to win. You don’t say that unless you k kw you are. I’ve lost my parents and my sister in law many friends and my boss is currently fyi g of stage 4 cancer and I think what he did was horrible but he thinks I’m just depressed Or it’s all me. Excuse my typos I’m crying and can’t see what I’m writing. Was he wrong to say that
