I hope you mean, to show him you like him :), Well, this should help :) READ ALL


Smile every time he looks your way. Flash him an inviting glance. Raise your eyebrows and shrug. If you're brave enough, wink! Great eye contact is ultra-effective.

Practice your gaze in the mirror. This way, you can perfect a confident, positive look of interest. Be sure to smile, too! Rehearsing also helps you avoid lovey-dovey doe eyes. Hold eye contact with your reflection for a full minute if you can. This will get you comfy keeping your eyes on your crush when the two of you finally chat. Don’t stare, glaze over or forget to blink!
Be way casual. Don’t fix your eyes on the guy from a distance like a tiger hunting down dinner. Pretend you just noticed him right before you reach him, then catch his gaze and flash a smile as you pass. Check out his reaction: Does he hold your gaze and smile back? If so, good. Repeat this process a couple times, until one of you is bold enough to strike up a conversation.
Strike up conversations when the timing's right. Tune in carefully to what your crush has to say. Guys love girls who listen well—it makes them feel interesting, which in turn makes them feel good about themselves, which in turn makes them feel good about you for making them feel good about themselves! Got it? Cool. Complement the listening with a compliment. While he’s telling you about that giant trout he caught at the lake last summer, take in all the details, and then say, “Whoa! You must be a really amazing fisherman! I’ve never had a chance to go fishing myself, but I’ve always wanted to try it.” Bingo! He’ll start talking a mile a minute—he’s gonna want to teach you everything! Next thing you know, you’ll be out on a lake in a canoe with your cutie.
Express appreciation for qualities that he happens to possess and interests that he happens to have (and mean it!). Be careful, though: Don’t act even remotely stalker-ish. For example, never attend his games by yourself—it’ll look weird. Just go with your crew, have a great time and, afterward, very casually pass him by—once—smile, and say, “Hey, that no-look pass you made was impressive!” A genuine pat on the back for a job well done scores major points.
Flirt. Whether it's laughing at his jokes, teasing him gently, or touching his arm, a little bit of playfulness never hurts.
Invite him out. It doesn't have to be as straightforward as asking him out on a one-on-one date. If you're going to the movies with a group, for example, ask him to come along. Use group activities to your advantage. In addition to bowling nights and mall trips, suggest your group throw a bash for your bud who has a birthday coming up. You be in charge of the invite list, and make sure his invitation is the first one to fly into the mailbox. Better yet, ask him and a bunch of other guys to help you and the girls pull this party off. A day of painting “Happy Birthday” murals and stringing up streamers can be bonding in a big way. Be sure to give him props for his excellent ideas.
Find out if he has a special someone already. You can beat around the bush a little:

What'd you do last night?
Do you hang out with different people, or do you pretty much stick with the same crowd?
Who do you usually end up spending the most time with?
Avoid doing all of the above with other guys.
Leave it be. Once you think you've got your message across, don't push it any further, but don't back off, either. The ball is in his court now.
