Depression battle

Not sure what to feel. I’m a lost soul at this point. I want to break things off with my daughters dad but I’m so torn. It’s just not going to work and I know it won’t but I don’t know what’s holding me back. He’s a very aggressive person, very demeaning, and loves to argue(EVERYDAY). I guess I just don’t think I can do it by myself. I think I don’t deserve better or deserve love. I am tired of being depressed and unsure of myself. I feel like I am slowly de pleating and crumbling inside. I just want to be great but I feel like I can’t do that around him. I just don’t know anymore about anything. I hate myself for feeling this way but i can’t keep surrounding myself with this negative energy, always being put down and feeling stuck. I’m alone, lost, depressed. I don’t know what I’ll do from this point on. :(
