I want to talk to him but I dont know if I should.

I also have a "friend" that I am pretty sure is hardcore flirting with him at this point. She'll talk about how much of a loser he is for his behavior (mind you, she was not involved with the group before they got aired out anyway), but she's never actually spoken to him. And online he'll reply to her posts and she'll complain, but instead of blocking him or ignoring him, she entertains it. She also thinks he's attractive and won't stop talking about him. Yesterday we 🍃, and got back to campus. He was outside, and I try to avoid him because every time we're near each other eye contact is made and I get sad and I don't want to deal with that. So I suggest we go inside, and of course inside is coincidentally being used by a teacher. We go back outside, and I ask if we can sit on the other side of campus because I feel uncomfortable being so close. And they refuse, so we sit near them and I have a full blown anxiety attack and leave. I don't feel like being friends with her any longer, and that wasn't even the first instance that I felt off about her. 

Anyways back to him. Even though a lot of people cut them off, the intensity of it is different. Like he knows he shouldn't interact with me and that I am genuinely hurt. He'll joke with everyone else, but I don't even give him the chance to do it anymore. And multiple people have told me that he stares, and I caught him staring and glancing. That's another thing, because I want to talk it out with him. But where would I start. Im just so sad, I loved him and everything ended so sudden. I hate high school.
