starting over

I’m trying to find my way out of a crazy relationship, but I really don’t know how to do it. it’s like no matter what I do I can’t make myself give him up. I’ve been treated so poorly for the past 7 months and I really don’t want to do it anymore. so why can’t I stop? why is it that I can never let go of the people who treat me so poorly? I haven’t made my own decisions since I got into this relationship because for some reason I thought it was okay allowing him to run my life. why is it just now hitting me that that is not okay at all? why did I convince myself that I deserved to be treated this way? I just need a way out. I need to get away from it but I’m scared I won’t be able to. I’m scared I’m gonna be stuck for a long period of time.
