Me and a gf were living together. We broke up and she finally moved out. The first night with out her i went to a bar and meet some girl. She came home with me and my ex was sitting in the parking lot spying. My ex was banging on the door for a half hour calling me and this other girl every name in the book. Turns out the 2 had mutal friends and became friends. My phone would ring and i would see it was the new girl on the caller ID. And answer and it would be my ex. They were hanging out together, that was fun
