How to get over a fuckboy😩

Ugh. I started like talking to this guy I met in school and we hooked up and whatever. Well I can see now he doesn’t care about me or have feelings for me like that. He’s just trying to be friends with benefits. I’m trying to just get over it but it’s hard because I see him all week in school. Like we’re in the same room together all day. There also this other girl who’s interested in him and he’ll start talking to her to make me jealous so I know if I just try ignoring him he’ll start talking to her and whatever. This is so dumb, I just don’t know how to let it go when Im around him all day 5 days a week😩
