Ever had a girl seem 110% DTF, everything going your way, and then a switch flips and shes different. What gives!

The Good Signs: She picked ME up as I was walking shirtless in our street and yelled me to come drink with her and her friends. She put on my T-Shirt (and found out later she removed her bra too). She came to my apartment next door for "shots" with only me. She said how to I pin this shirt and I showed her a way without in the process completely lifting up her shirt which she was totally relaxed about. We were making out, I lifted her up by the ass to carry her to my bed....

The bad signs: She hit a wall and said "I can't do this, I'm not this type of girl" --> um what? I said: "Well you don't even know me so take it easy eh?" She never messaged me after taking my number.
The good signs: Today she accepted my FB request.

I think she just didn't want to come across as slutty and being drunk realised the sitution, but she shows intrigue and I'm optimistic about it -- she didn't have to accept the Friend Request right? What's the right way to play the mixed signals??? It's hard to gain confidence when a girl says I can't do this eh??
