If a boy has a crush on you, then he’ll go out of his way to try to impress you. He’ll want you to think that he’s brave, exciting, cool, or even wacky. The next time you’re around the boy who might have a crush on you, see if he starts trying to say or do something that is calculated to impress you. If he tries to show off when he’s playing sports, brags about his awesome weekend plans, tries to do something crazy like jump in a pool with his clothes on, or engages in other behavior that seems calculated to impress you, then he may have a crush on you.  Watch him closely when he does something “impressive.” If he keeps looking over at you to make sure you’re paying attention or to see what you think, then there’s a good chance he has a crush on you. Though it can be hard to know what he does when you’re not around, try to get a sense of whether he starts showing off more when you’re there. For example, if he starts telling a ridiculous joke or showing off his ability to juggle oranges just moments after you walk in the door, this behavior may be for your benefit. This is another dead giveaway that the boy has a crush on you. If he’s jealous of the guys you hang out with, then it can only be for one reason: because he likes you and feels threatened by them. Guys have different ways of showing that they’re jealous of other guys. He may just make fun of the guys to you, be rude or aggressive to the guys, or just roll his eyes and turn away from the other guys in your orbit. If he’s jealous of the guys you’re around, it’s because he wishes he had more quality time with you instead.  He won’t admit that he’s jealous, of course. But if you find him constantly talking about what a loser your friend Jake is or asking you why you’re even friends with a weirdo like Steve, then this is his way of saying he wished you were spending time with him instead. If he puts down your guy friends to their faces, then he’s definitely jealous of them. Though this behavior can be a problem if he’s being really rude, if he’s just not...
