I can’t argue with my boyfriend

So today I was at his, and we were play fighting and jokey arguing but he always takes it too far and ends up hurting me emotionally and physically so I’m always in a mardy. But today he basically made up some excuse like can you leave I’ve got stuff to do... when he was meant to spend the whole day with me so he’s looked up my bus time and took me to the bus. At this point I’m mad because he’s just told me to leave so he doesn’t have to deal with me. I’ve confronted him like why do you want me to leave when I’m mardy but every time your mad I stay. Then he goes on to say yeah but you can mad over dumb shit and then he leaves me at the bus stop. So then now he’s left he’s going on to say you piss me off, just getting mad and I’m just being blunt and I am saying stuff like well come back and out see me so we can talk. He’s saying stuff like are you trying to get me mad, I need a couple days to myself, your not gonna be hearing from me ect.

I feel like it’s acceptable for him to get mad and I always calm him but he moment I’m mad he just doesn’t even try to calm anything he just also gets mad built over reacts more so I feel like the bad person. But normally I sort stuff cause I don’t wish to leave him and he somehow persuades me it’s my fault.

What do I do can someone help cause I can’t keep doing this and making my self feel like shit every time we get into an argument
