Good day, slayers. Could you explain this to me please?

On my second date with a Plain Jane, we went for a couple of drinks. It lasted a while, and all the buses to where I live didn't drive anymore. The only option for me was a Taxi, but she proposed I stayed the night at hers (her place was near). When we went to bed, she wouldn't undress. Guys - nothing. Not even socks. Nevertheless, we made out a lot. She even held my hand the whole night. Two days after, Plain Jane doesn't even want to look at me when we're in class (college), and barely acknowledges me. That was Thursday. I soft next her and she texts me yesterday to come to her place today at 10PM. What do I make out of all this?
