Relation ship advice 💙

Okkk sooo Im in Highschool and I have this exxx🥹 he was terrible to me he rarely spook to me at school.But outside of school he was a total sweet heart. We ended bc of a fake friend I have and will never trust again lol 🤎 His gf talks shi about me 25\8 and I have beef with  her deeper than him and bc of this we haven't spoken in 2 yrs. But that has nothing to with what I'm asking which is I stil have deep feelings for him that I cant ignore ADVICE ?🥰🥰
