If A Guy Asked Me To Be His Girlfriend How Would I Say Yes?

Call him or when you see him if you want to say yes, then just tell him I thought about your question and if you still want to go out my reply is yes, if that is what you want.  Don't wait too long on it.  He may get shy and feel like you don't like him.

Well, if you like him, you say yes! Don't tell me you forgot how to talk already.
If you did, write him a note and say yes. Tell him you'd like to be his girlfriend

I think that you should talk to him asap. && I do agree with lisamarie1 that you shouldn't wait to long or he'll think that you don't like him and don't want to be with him ok..So whenever you have the chance tell him that you'll be happy to be is girl..So best of luck to you in the future.

I would write him a note saying yes I would like to be his girlfriend
