Step1:
Be sure that his attention is what you want. Don't try to get a guy to look your way, because you want attention and you want to feel good about yourself. You don't want to lead someone on like a puppy taken out for a walk. You could end up in a very awkward or uncomfortable situation...
Step2:
Be yourself. Everyone probably says this, but it's true! No guy wants a girl that pretends like she is something she is not. Show him that you are a good friend. If you want to find out more about him, don't stalk the poor guy. Just find out about him from his friends who you trust. For example, ask them about his likes and dislikes, what music he is into, if he likes anyone, etc. Be confident in yourself, and it will show that you are an amazing person. Don't be someone you're not. You want him to like you for you.
Step3:
Try to become his friend. Get to know him better. Yes, you might like him, but first, become his friend. Start liking things that he likes, but don't get too much involved. First, try by asking him questions. Don't take it wrong if he says something bad about what you like. That's just his opinion, so don't want to do that because he will like you better, just try something different, but dont stop doing what you like to do, because he might like someone who does what they like; if he doesn't like you for who you are, then let him be. Try a new hairstyle, new clothes, etc. It's a good idea to change things up once in a while. Try being that girl who is different from all the other okay looking girls. Give him the eyes, guys love when girls look them in the eyes.
Step4:
Smile and make eye contact. Whether closed-mouth or open-mouth, do it.
Step5:
Be cute! He will come over and talk to you. Don't be a total wallflower, but if you're just reading a magazine, try and look cute and wait until he can't resist and he might ask what book you're reading... and take the conversation on from there.
Step6:
Flirt. Do it as much as you want, but remember that too much flirting (especially with other guys) will likely get him to take notice, but perhaps not in a good way. Don't do too much, but not too little either.
Step7:
Hang out with him often but not too often, you don't always want to be hanging around because you might look like an annoying bug that's always around and never goes away.
Step8:
Be assertive. You are the girl. You have the power. A lot of guys are shy and awkward around girls they like, so don't hold back. Do what you want to do. Boys like a powerful girl. Be decisive. Tell him what you want him to do, etc. Just don't get too bossy.
Step9:
Don't be a slob! It's a real turn-off for a guy when he notices a girl hasn't brushed her hair or wears the same outfit every other day. Even if you don't fall within the typical expectations, just looking presentable is always desirable for a guy.
Step10:
Just Talk To Him. When it comes down to it, talking to a guy, and flirting with him will get his attention, and if it doesn't then nothing will.
Step11:
Walk in front of him. It may be very simple, but it works. When coming out of the class, or playing in gym class, just walk in front of him, and he should be able to notice you. If he walks in front of you a lot, he probably likes you.
...
Some other things about the same subject:Never ask him out through a friend! He'll be creeped out and he might just say no.
Remember that the boys rarely get asked out because they're the ones who usually do the asking. Take a risk and ask him out! On the negative, he might feel flattered and politely decline. But the positive WAY outweighs the negative. He probably has NEVER gotten asked out by a girl. When you ask him out, you're differentiating yourself. He'll notice and feel complimented, you'll make him feel great about himself AND about you, and you'll stand out in his mind. Also, if you've read the signs already and have a feeling that he might already like you (but maybe he's shy) the odds are very high that he'll agree to go out with you!
If he doesn't seem to be getting all the hints after a week or two that's okay. It doesn't mean he doesn't like you; it just means he may not be ready for a girlfriend right now or that he is too shy to show emotion back. If after maybe 3 months of being flirty then he probably isn't into you as much, it could still change. It's completely up to you how far you'll go, how hard you'll try, how long you want to keep it up, etc.
Don't force him to like you. If he doesn't, don't feel too bad, he's the one who's missing out. Let him meet you halfway at least. Like everything else, things can change over night. Sometimes you need to give him some space to think about the idea of you & him.
Make sure you listen to him and not just keep babbling about yourself maybe you could learn a little more about the guy you like than just his hair color, eye color etc.
That's it... Guys are easy..
