I asked girl if she would go out with me and she said she would think about it Wat if she say no to me ??

if she says no, move on, you're not depended on her. don't take rejection personally, take it like a lesson, one step forward success, nothing to worry about. its her loss

dont make woman too important,thats the mistake, dont make her the source of your happiness.

if she says yes = more fun

if she says no = you're happy on your own anyway

be confident ;)

I think that is a no....but erm how to help you can just play it off and walk away....really nothing you can do

If she has to think about it, she already has said "no". Try to move on.
