Honestly if a guy likes you he is going to respect you and act differently around you. He won't turn his back to you, but instead will try to be close to you. He'll look at you a lot because he wants to look at your beauty :) He'll try to catch your eye and stare at you for a long time or make silly faces at you.

I am pretty shy when it comes to a girl that I like, despite being a person with constant verbal outbursts. When I am with a girl that I like, I try to ignore her in any way possible. It doesn't sound like it would make sense, but sometimes reverse psychology does work. Sure, I have no idea whether or not she likes me, even though she knows that I like her. It was obvious when she found out that I liked her. I told one of my girl friends (not girlfriends, but girl friends (girls who just happen to be my friend)) that I like this particular girl, and then I would ask them to tell her (and only her) that I like her.
You don't! Its really unfortunate but you have to deal with it, i guess you only really know if they're not cheating on you.
