I had a girl do this to me. What would make her do this? We were (are?) pretty good friends, but I haven't been talking to her much lately since I asked her out and she told me she had a boyfriend right now.
Why would she give me her number if she has a boyfriend?
What Girls Said
If you are pretty good friends, then giving you her number is no big deal.
Or, she may want to make her boyfriend jealous.
What Guys Said
think about this man, if you ask one of your boys for his number does he think you want to go out on a date with him? NO he gave it to you because your friends. same thing with girls, just because she gave you her number doesn't mean she wants to go out with you.
