There is a girl a like at my school and I told one of my best friend that's a girl and she told her and she seems to pay more attention to me now and look at me more. And I asked one of my best friends that's a girl if I should ask her out but she said wait a little. So I don't know what to do. I really like her and everything and I think she might like me

You like her, yeah? Then just up and ask her out already. It's win-win for you either way. If she says "yes", you've got a date with a girl you like. If she says "no", you can stop tormenting yourself with mental whatifs and wasting time with your indecisiveness posting questions on AMHD. Plus, now that your friend has let the cat out of the bag, your cutie is probably wondering "What's he waiting for?" and then she'll be posting on here wondering "OMG, Does he like me!!?" It's a vicious cycle. Please, end the cycle - ask her out. Carpe Diem...

Just talk to her and get to know her better. There's no rush to ask her out instantly. Let her get to know you better and you should get to know her better. That way, she would feel more comfortable if you asked her out.

Talking to her is fine but if she already know you want to ask her out you may want to tell her your intentions

Talk to her, and not your friends. What are you, in high school or something?
