What does this mean??! help?

Ok, so I have this neighbor that I've known since I was four. We were friends then we grew apart, and now we're friends again. He is one year younger than me. He went out with this girl last year and I can tell she's not over him. She said on facebook that the football game was gay just becasuse "he" wasn't there. And someone commented and was like Thomas I'm guessing? (Even I know he usually doesn't go to the games.) Then I think they might be going out again but idk! Thomas said he wasn't going out with anyone and that he didn't like anyone... but it seems like they are. So I really shouldn't even care, and I'm trying to tell myself that I really don't care. Because I DONT like him. I don't. So why was I fricking crying about it earlier?? And listening to stupid slow songs on youtube? What the flippers? DO I like him? I don't know!!!! HELP GIVE ME ADVICE!!!!!
