Why don't i want to leave my abusive relationship?

You sound scared to be alone and you've gotten use to being with this guy. but nothing is going to change unless you decide to do something. Find a guy friend or your father and tell them whats going on. Tell them you want to break it off but you're afraid to get hurt/ be alone when you break up or that you may relapse into taking him back again. Meet the current boyfriend in a public place, don't tell him why just act like normal, but meet him there separetly with your father and or a guy friend who could take the boyfriend if need be (i mean that they could kick his ass) and break the relationship off. After that go stay with your father and or the friend so they can watch after you. While thats going off block his calls and delete him from all your social media. If you think this is good advice i hope you do it and i hope you let all of us know when you did. If you need anything else feel free to post on my comment and I'll get back to you asap
