Is this the final straw?

So I've been dating my boyfriend just over 6 months now, in the space of this time he's broken up with me twice, the first time panicking that we were going too fast (he initiated everything) the 2nd time due to mental health issues and both time I took him back after lots of discussions and talking. Everything was going ok and then he started acting strange again, broke my collarbone recently and during my recovery I spent a weekend down at his house and he couldn't have made it clearer that he didn't want me there. As soon as I got dropped off and he took my things inside he didn't speak just went straight to the gym, came home gave off about having to go out and then got very drunk. I felt so unwanted and so hurt and upset.

recently we fell out which ended in me telling him we needed a break ( we are self isolating in different homes) after he snapped at me and had a go over me going out for a walk. I gave it one day before my emotions got the better of me and I told him how he's been making me feel that he's been being really insensitive, rude and dismissive.

I brought up an issue I had with him knowing about this girl who had previously bullied me, who still makes me extremely anxious and sad and about him liking all of her photos on social media including ones of her dressed provocatively and in very little clothes. This along with another girls profile even though he knows at the moment I'm extremely insecure about my looks, that I've been so depressed
