AHHHHH!!!! She has a boyfriend!!!!!!?

She's hot. I should have known she'd get asked out. What should I do? Even though I don't know her boyfriend, I feel like punching him when he touches her. He's a player for sure. I hate it when they go off together to....kiss. It hurts. I was thinking about ignoring her but.... I don't know if I can. I want to be near her... what should I do?
