It’s hard to be friends with people you LUST after, and she’s sent mixed signals, possible head games, etc.
I would not contact her for awhile and see what happens and actually move on too.
Perhaps all she wanted was to go out with someone and was oblivious to your feelings?
Could be dating multiple people and someone suddenly asked for exclusivity or she now has chosen her man?
Relax, don’t have high expectations, and you are more likely to not get hurt in this process.
Best of luck to you!
