Ignorant bf?

Everyday my boyfriend does something to piss me off. He will either purposely hurt me and then I will get mad and hurt him back. Then he will go crazy as though he didn't do anything to deserve it. He's supper annoying throughout the day. He has these temper tantrums after he gets mad about his videogame and then he will get mad at me about something that happened the day before. Wtf is his problem. Like I said this is everyday. We get in arguments about things that he over exaggerates about all the time. We never see eye to eye. What do I do? Why do you think this happens. Obviously we don't take each other seriously and we both act immature in fights. What's our problem? Any ideas? I'm open for any opinions or judgement!
