Don't over think this! If this guy said maybe, chances are he just hasn't thought of it much. He probably wasn't trying to put a hidden meaning behind his words so don't take them like that. Think about this: A maybe is better than a flat out no! I think you have a chance with this guy. Go for it but don't complicate everything he says!
I know when I say maybe to a girl, it generally means I want to get to know her because I don't know her enough to say yes. So I would suggest speaking with him, just casually chat, see what will strike up!
It means no.
It means maybe.
It means he has got you as a girlfriend maybe it is because it is hard to court you.
It could be, or maybe he doesn't love you anymore.
It means that he could be mean or heartless, or maybe he is just cold like freezing
what does it mean for a guy says you are my angel
Maybe he doesn't like you.
Maybe he is scared to ask you out, so tell him your real feelings!
It means he's nervous but may not like you or maybe does
It means he doesn't like you!!!
You can't really tell what it means. Maybe he likes you. He wants to protect you.
When someone says a guy is under the radar that usually means they think you're gay. They usually say "gaydar".
