My boyfriend of 6 months cheated on me by saying he was home with his parents when he was really out at the movies with another girl who is also a junior. When I confronted him he made fun of me in front of a group of people from our school saying I was just something for the summer. I dumped him but now I also want to humiliate him. He swims at 24 hour fitness getting ready for the swim season and he uses my combination lock so I was thinking of going in there and stealing all his clothes and wallet and cell phone and keys while he’s swimming. He’d get laughed at and have to walk home in just his swim jammers (spandex shorts). Is this a good idea? Suggestions?
