Okay so I was talking to this boy and it wasn't anything more than friends although sometimes when I'd say like " i gotta go" he'd be like aww😕 and when I'd text him like I'm back he'd be like yay😊. What does that mean?? We have 6th period together and he's always make an excuse to talk to me he even asked me to be his partner in a project.(but I got assigned to another girl) now he doesn't really talk to me and he never texts back. Is he just being salty or not interested??
