Me 23f needing advice on how to leave boyfriend 24m that I live with

Hello! I’m 23f living with my best friend and boyfriend 24m. My best friend and I have lived together since we were 20 and my boyfriend moved in with us in April.

Living with my boyfriend, I’ve noticed some habits that don’t align with my lifestyle, he drinks a lot, is high a lot, he doesn’t have a lot of motivation or drive and when he drinks he can become combative and argumentative and downright mean.

We had a situation where he left my friend and I in boston during a bar crawl for Halloween because he said I wasn’t giving him enough attention and he started cussing at me and told me to find our own way home and left to find his friends. He called me after and was swearing at me and calling me names.

The next day I made him go home to his parents for a few days and when he came back he apologized and said he would change things but ever since he’s been back I just don’t want to be around him, or let him touch me, and I just feel constantly annoyed by his presence.

In the past if we’d get into an argument all I wanted was to make up and now all I can think about is how much I want him out of my life. The worst part is he is doing better, he is trying harder and being better but I feel like I’m rewarding him for doing the bare minimum and I just can’t shake the feeling of not wanting to be with him anymore.

I guess I’m looking for advice from women who have left someone they live with or have gone through something similar. I’d also like to note we moved into a new apartment (all three of us) and him and I are on the lease because my roommate was having credit issues so it does make it more difficult where I can’t just ask him to leave before our lease is up.
