Hey, Tonic here from Australia
I wouldn't be too concerned there champ, the whole "morning after" situation is a good way to gauge how the night went, but it is never a clear indicator as women feel more vulnerable in the morning (no makeup, no clean clothes, nothing to hide behind).
It sucks that you may not get to see her again, but are you that bothered?
Look more into what you want for yourself. Is it a lot of one night stands? MLTRs? A girlfriend? Be more concrete in what you're after and your responses from women will be the same, they'll respond better to your confidence and you'll be able to progress with them, or accept that it wont work and leave it on a high.
Being hung up like this over one girl's bizarre response is a form of one-itis, and obviously has you thinking about it. Stop thinking, accept it, move forward, and learn that bizarre responses are more often than not the result of clarity in your own desires.
Hope this helps you buddy, best of luck,
