My Delusion Confusion

So, pretty much I've almost always been good at telling when someone likes another person or not, you know as in they want to date them. But the one thing I've never been able to tell is whether someone likes me. I've tended to let my delusions get the best of me when I think some girl likes me. For example, right now I think that two girls I know want to ask me out. Of course I'm not going to just walk up to them and ask, I need to save face. But it just makes me wonder. Cause at my old school girls liked me, I'm not exactly an attractive person but I tend to make them laugh a lot. So at my current school I'm just stuck wondering, and confused, about whether these girls like me or not. Both of them I would say yes to of course. And then I start wondering again, maybe that's why some guys pick on me telling me no one likes me, calling me ugly, cause they jealous. But that's a really fucked up ego speaking. One everyday will walk up to me and go, your going to see him today. I at first didn't give a fuck but then slowly my interest was piqued to the point I have to keep asking her who she is, she's given me some clues but so far some of them have been off. Then there's another that I thought was creeped out by me, which she probably is. After I said some stuff to her then current boyfriend about how I'd love to fuck her she couldn't talk to me. Then recently I've noticed her looking over in my direction in class and she's started talking to me again, weird. So that's why I have the idea that they like me.
