Boy confusion

Hey guys basically I 15f have known this guy 15m since I was 12 but we’ve gotten close in the last year I’d say and idk he’s funny kind and good looking I like him I won’t lie he makes me happy but idk if he feels the same we snap and message 24/7 and talk about deep stuff and when we snap he send me shirtless snaps like full on abs and I send him like flirty ones back overall the vibe feels pretty flirty but idk I’ve never been in a relationship so I need help what do u guys think
