<human>: I met a girl at a party after a night out and we hit it off pretty well, I went from being a virgin who has never kissed a girl went to spending the night in bed with her. I personally opted out of having sex with her since i wasn't sure how sober she was and didn't want any problems legally etc. 

We slept together as I held her and stroked her hair as we cuddled she told me she would date me if I asked and I just panicked and passed it off, but I think i like the girl. 

After waking up me being an awkward guy after waking up I held her hand and stroked it whilst sitting on the bed and then realised what I was doing and felt really embarrassed. She was stroking my hand back though , but I couldn't say a word to her she left the house after giving me a hug but we didn't speak at all, I added her on facebook and she accepted within minutes but I feel too embarrassed to send her a message it's about a day on now and I feel like my chance is slipping away.

I'm not sure what the next stage should be, should i get her number and text her or try talk to her on facebook, or another solution. 

Thanks for reading and thanks for advance for the help!

<bot>: Met girl, hit it off, first kiss, slept with her not much left out except sex too embarrassed to talk to her, both quite drunk but seems like she remembers, showed signs of liking me.
