Everytime I'm happy in a relationship, I slowly begin to find flaws everywhere until I'm not happy anymore. Because of this, I already cheated on 3 boyfriends. My boyfriend right now knows about that. He thinks, everything is still great. But now, after three months, I feel again the urge to sleep with other guys and have a small adventure. I don't want this. But I don't know how long I can cointain the urge this time.
