Crazy

Me and my boyfriend were doing well. We get into small arguments that I'm not gonna lie I get intense about but we have been able to make it through. Tonight he invited me to dinner with his family and it was great. After dinner he dropped me home. I asked him to go to the cvs for something before that and He agreed. We get there and I tell him to enter the cvs a certain way and he says I'm wrong and goes another way. I'm a little annoyed about this be asue this is not the first time I'll give him a direction to go somewhere and he won't go or he will devalue what I think. I tell him how I feel when he does this and we get into an argument because he starts giving excuses in my opinion on why he does this. He starts screaming like a crazy person saying he can't handle it, and spazzes out and hurts himself ( hits things and gives himself a couple bruises) I just go hoome cuz I don't wanna deal with that. Idk what I'm supposed to do or if this is stupid. Probably is.
