There's this girl who I've known for 2+ years now. I think I started to get feeling for her last year in June, but didn't notice until September. By then, it was already too late. She has a boyfriend, and it's been roughly a year but I can't shake these feelings. It sucks too cuz he's such a prick and genuinely a terrible person. I'm scared that doing nothing means I lose her, but saying something might be worse. I've openly expressed my concerns about him, but she thought I was joking or overexaturating. I don't know what to do anymore.
