Abusive relationship, should I leave him or not?

I have been with a guy since 2016 and within 4 months he started verbally abusing me. I chose to be with him despite knowing the fact that he have severe anger issues. But in 2021 he got physically abusive for the first time, he said it won't happen again and I trusted him. In 2022 I finally broke up with him but reconciled in Jan 2023, I loved him since I was only 15 years old maybe that's why I kept taking him back no matter what he did. But in June 2023 he again got physically abusive that too many times. He never stopped being verbally abusive. I left him but now he's coming back again and again just for me to give our relationship another try and that he will definitely change this time or else if something ever happens again I can leave him then. I don't know how to make him understand that I can't be with him anymore my mental health is getting disturbed. Or should I give him another chance and trust him this once?
