Just chill and wait for her to call you!

Don't make any attempt to communicate with her until she does. Maybe some distant is good.

But be prepared for the worst, but don't worry about the worst. Over-thinking what is he/she doing kills more relationships than anything else when you actually start to believe it.

Next time you talk to her, express yourself and don't let it hang any longer. If she doesn't want to give you time to talk about it, well, it's time to find someone who will.
