Shaming

So I went to a party and tried to hook up with some guy but he was to drunk and it didn’t work. My best friends brother( ugly boy) tried to hook up with me because the girl he liked curved him. Now he’s trying to spread around that he caught me master bating by myself in the bathroom witch never happened. I let my friend know the truth but should I confront him! I’m so pissed about it ! Has this ever happened to anyone else we’re a guy tried to spread a rumor about you because you didn’t give it up
