My boyfriend gets mad at everything I say now…

He used to not be like this but we’ve had an issue with my mother not liking him and it’s made it hard for us to do anything in our relationship. He blames me for that situation because it is my fault but he never fails to remind me which at this point is now so hurtful. Like I know I messed up I don’t need to be constantly reminded of my mistakes. And now it seems like everything I say pisses him off and causes him to ask “why are you like this?” I’ve decided to give him a break but I’m scared that after this “break” we’re going to go back to this. I feel like I have to walk on eggshells because I don’t want to piss him off but I wanna have a conversation with him and see how he’s doing. Idk what to do anymore. Should I just leave? Try to give him space?
