We got along pretty well and she gave me her # without me asking for it and then she just started giving me the silent treatment. What does this mean? What should I do?

Can you provide a few more details?

Did you end up asking her out?

How long have you known her?

Are you interested in this girl? If so, please give us more details and we can try to help you out.

Did u do anything to upset her? Us girls are very upsettable. Either that or she is playing hard to get. Try asking her out. See how she feels. Good luck.
