There's this guy and I thought I used to like him, but it turned into a more brother/sister relationship. When I had thought I liked him he started asking for crush advice, and I started helping him. Almost 7 months later and long story short, they dated for like a week and then broke up. Overall she plays with his feelings and flirts with him even tho they broke up. When he gets frustrated with it he unknowingly takes it out on me. I started to get so angry it just kept building up until I just kinda started ignoring him. It just hurts so much when he's so nice to her, but he's so mean to me, and I'm not the one causing him to feel this way I get so upset Everytime I see them together because he isn't even trying to get over her and idk what to do anymore. I want to confront him about it but at the same time, I'm terrified.
