if you really liked her, you wouldn't worry about your rep.
Just because people act a different way or dress differently doesn't mean they're not like you or me. :/
You dont.
You can do this by approaching her and simply asking, “Would you like to have lunch with me?”

There is no way you can tell a girl you do not like her without ruining your friendship! One thing you might try, is if you have a date with another girl, set her up with a date with another guy and the foursome go somewhere together. You will have gotten her a date and done her a favor. You will still be friends. You will have told her that you are not going to date her.
You should not try so hard because if you do your relationship status and reputation.
I am a girl and I would say that you should talk to her first saying, "Why do you like 'Mark'?" and if she says something like... "Becuase he is cute and funny why?" then tell her that you like her and that you could make her happy. If she says no then accept that she is happier like that. its all you can do.
Always be kind to everyone and keep a good reputation with other people. Keeping a good reputation will help your general aura and boost your confidence.
The one that likes you without a girlfriend.
honestly you can't because it's happened to me and I seriously wouldn't risk it because teen relationships don't last forever.. take it from me
Well make a move like put your arm around her or talk to her and say why don't we take this to the next level.
Stay friends!! Dont risk ruining your friendship. If she starts to feel the same, I'm sure she will let you know. Don't rush!!
If you love the girl you are with and she is kind; caring and loves you never mind what your friends are saying about her. If they are warning you that she has a bad reputation; is flirtatious and will hurt you in the end then that is the time to listen to your friends.
