I have this issue where I constantly check my ex best friend facebook to see if she talks behind my back...I stopped for awhile but then I got tempted to do it again. I know it's wrong to invade someone's privacy like that but I feel like I always need to check what she has to say about me in her msgs. She said some mean things before and that's when I knew I could no longer trust her. How do I stop getting tempted to check?
