What will you do ?

I overhead my boyfriend tell someone I disturb him with calls. This was after he had been mean and cold and I was asking how I could love him better . That day I went by his and called him but he ignored my call. He didn’t know I was in front of of his door and I overheard him say I disturb him with calls. When he finally returned my call, he apologized for not seeing my call or message (which he intentionally ignored because I was in front of his door by the way) but I was calm and never called him again. The next day he called and asked to talk about what happened and I told him there was no need and that he said what he said. Then he hung up without saying love you just to trigger me because he know how much I hate that, he was expecting me to call him back but I never did. He noticed I stopped calling him and he stopped calling me and that was the end. He started doing things to intentionally hurt me but I ignored all. There were sooooo many things before this and leading up to this. I wouldn’t even know where to start. What would you have done in this case ?
