What do you do when a girl says she likes you?

Answer 1

You ask her out on a date.

If she says no, Shrug it off and move only. There will be potentially lots of times this could happen, by not taking it personally you will move on easier.

Personally, i think you wait for her to say something, say it once more, but look into her eyes so she knows you mean it, trust me it works, if nothing happens from there do the above

Answer 2

When a girl says she likes you, you have to think if you like her back. Then if you do, you can think about asking her out. But if you already have a girlfriend, then tell her that you guys can just be friends. If it is a creepy girl then just say "Ok" and walk away!
