Bf has anger issues

I swear I can do something so little and he will bitch and yell and bash me. For ex., he’s cheated on me a lot in the beginning of our relationship so he knows I have some triggers. He says as long as I come at him correct he will reassure me. The other day he said something that threw me off, he said it was nothing. I call back again later saying I’ve had it on my mind and want to talk about it. He goes to say “you’re annoying as fuck u don’t listen” and calling me bitches. Even while I’m crying he keeps going and going.

Then just now. I called and he said he didn’t have a lot of data, so we hang up. I call back only because I needed him to quickly send me money for our sons medicine cause I was heading out the door to get it. He starts bashing me again, before I can get a word out he’s calling me bitches yelling saying I don’t listen.

Should I try to get him into therapy or just don’t waste my time and just leave?
