It depends. If you are stilling wanting more then I would let it go. If just friends then I would tell her you just want to be friends and see what she says.............

It can get a little intimidating in that time. But if you want to keep a good friendship you both have to look past the setback and act like friends. Because you are friends. Just make sure your actions don't show that you like her more than just friends. That could annoy her. Don't avoid her, because then she will think you don't care about her because she said no to you. Ignore the feeling and it should disappear when you guys get along again.
