I keep hurting my girlfriend
One time my girlfriend, who I loved and considered perfect, cheated on me and it shattered what I thought about her. Before I knew she cheated on me (because it happened months in the past) I actually cheated on her and when we broke up because of that she desperatly wanted to get back with me. It was during that time I learned she cheated before me and it changed everything, I hated her for it. I found out over the months of us talking on and off she was obsessed with me and even though I hated her for cheating I still had feelings for her and we eventually got back together. We are back together as of right now but since we have been back together I have just been lying and tearing her apart. Since she will not break up with me (I'm pretty sure she's obsessed) I just keep hurting her. Most of the time I just lie about what I'm doing and she stays very happy but when she finds something out or I slip up she freaks out and there's drama and we fight but I never care because I know I can get away with it and I know it hurts her and she hurt me and I just can't forgive her for what she did. I love her but I just keep hurting her and its to the point that I know I'm doing it because at first I didn't know what was wrong with me. Why am I doing this to her? Is this normal?
