What do I do?

(I’m going into Jr yr of high school) & last year I re connected w/ this guy from middle school when he popped up in my English class, I crushed on him (more like I wanna get in his pants not like deep shit 😭) & pretty much everyone eventually knew in that class we were screwing e/o & its continued all summer.... well I peeped some crap on Ig & found out he’s still “with” his ex, before we had sex I asked him & he said they’re over & it’s a sensitive topic(lie) soo I’m starting to realize they’re not dating dating anymore but they’re still talking & from what i can tell shes got him on lock ,, unlike him. This year shes coming to our HS & me & him have classes together & they don’t (she posted her schedule) me & him also r supposed to have plans tomorrow... what should I do
