Please tell me do I leave him or stay until I hate him.

My boyfriend and I have been dating for like 2 and a half years now and he used to be so sweet and carring and all but I tormented him emotionally so much he became detached so skipping to today. He's having his exams so he's not free to talk to me even for 5 minutes a day but goes out with his friends everyday. But today he went out I said that oh you should study he was like oh I've timed everything and have have an hour free. And I was so friking hurt and went quite and at that exact time his dad called him so he put me in hold and I ended the call and I didn't even think that he'll call me back or ask me how I am like I don't even expect normal human decency from my own boyfriend because I know better now. And yk he came home 2 hrs later without calling or texting me even once and then shamelessly texted me "👽" this.. when I didn't respond he called me I was honestly shocked but still didn't pick up so he called again and when I picked up he goes why are you not maintaining streaks on snap. Like what?! And then he got angry because of that didn't ask, didn't talk about that. And hasn't texted me since. Yk he never tries to solve any issue or conflict btw us even when I try he js acts like Nthg has happened. He was never like this but it's been years and I've made my piece with it.
