mixed feelings

Have you ever been in a situation when you don't know what to do?A situation where someone could get hurt? Lately, I've been feeling that my girlfriend don't even care for me or even like me. Our relationship is like whatever to her and she doesn't even care. I know I don't deserve this kind of treatment but I'm still putting up with it and I don't know why. There are times that I just wanna break it off but there's always something pulling me back. Maybe its because I really really like her. I know I could be better off with someone else out there. I deserve someone better and I know that. I hate it when my girlfriend trips off of the smallest shit ever. She gets mad for something that's not even that serious. I just wonder how much more pain she'll cause to me if we do keep on going out. By far,she's the worst girlfriend I've ever had. I knew that I should have never went out with her and just stayed being friends with her. This is 1 of the worst decisions I ever did in my whole life. I never had a girlfriend that would say "I don't care anymore". Man fk my life. As much as I want to stay with her, I don't think I could. I like her and all but I deserve better. I hate people that are stubborn,hardheaded and ignorant.
