it's complicated

Me and my boyfriend have been into a argument every night for the past week from 6pm to the time I pass out. The arguments consist of me my sh*tty sex and how I'm boring how I suck at talking dirty and being impulsive. He calls me childish for being upset when he calls me names like b*tch wh*re ect.. I have a past of being with guys who mentally abuse me this guy says he's bipolar but won't go get help and takes the anger out on me, but then he's nice and says he loves me and he wants me to talk him through his anger. I tried it once and got yelled at. I am just curious how the f*ck to get over this cause he's a b*tch when he's upset. Anyone else have this issue with bipolar boyfriends/husbands/ect?
