I need advice on how to get a girlfriend in Highschool?

There is a girl I want to ask out. I know she is not with anyone, but I am not friends with her yet. I have a friend who knows her and i have already told him i like her. What should I do next?I need advice on how to get a girlfriend in Highschool?
If you really like this girl, then I think you should ask her out. But first, try to get to know her better- see what she's like. She may be completely different than what you think. One time, there was this girl in my math class, and she was so attractive and so intelligent. So one day after class I asked her out, and she acted like a complete moron. She was so conceited, thinking she was so smart. So yeah. Get to know the girl better. And talk to her, so that she can get to know you. Make her realize that you're a good person and would be right for her. You're chances will be better. I mean, it would be weird if a stranger was to ask you out, and you knew almost nothing about them, right? So go ahead and try it. If she rejects you, don't worry about it! There are lots of girls that would want to go out with you. If you never try, you'll never know. So go ahead and take the risk. All you'll use is a little self-esteem, but at least you won't be wondering if she likes you or not. Take the risk! Good luck!I need advice on how to get a girlfriend in Highschool?
u go up to her, and ask her out
ask her out or you could first start being friends and get to no her
Check your image first. make sure your hair, teeth, clothes are good. Be confident but not cocky %26amp; try to talk to her, if you cant think of anything to say, compliment her. Myself being a girl I know this would probably work unless the girl is just stuck up. She would be flattered and feel good about herself. Wouldnt you like that? well try it. comment on her hair.. or outfit. I wouldnt go into purses or makeup or something ;] lol. Just be relaxed. I am sure it could go well. its not that hard to tlak to people in High School is it? GOOD LUCK!
You should get your friend to ask her if she likes you so you have an idea of what she likes.
find out something she likes, bowling paintball movies arcade games what ever, and ask her if she wants to go. well first make sure she know your name
all u have 2 do is give her flowers in her locker and put a note and ask some of her friends and dress 2 impress her u r welcome 2 ask
make contact with her then talk
hang out with your friend and have him invite her, get to know her, then you can talk and hopefully if everything goes right, you will become friends then a couple. thats pretty much how i got my first girlfriend.
if you have a class with her, talk to her about class, then go from there, if not, just have your friend introduce you and go from there, make some eye contact when ur talkin to her and she'll admire ur confidence, chicks love confident guys, once ur friends with her ask her to a movie, then date her, then... yea, get it, make it wet
