<human>: Condense the text into a few key points

So there's this girl I met fairly recently, she is very close friends with my roommates. I have gotten the impression the last few nights when we were drinking together that she was into me. Friday night we had a party at my place, went to the bar and probably only stayed for half hour before we left together, as she wanted food.  So we went back to her place, hung out and talked for a while then she invited me to her room. We had sex, or at least tried before we both gave up (too drunk) and she says "do you want to just cuddle tonight and try again in the morning?" .  So flash forward, we both get woken up ~ 8:00 and we just talk and she was supper cuddly, hand holding, kissing etc, we had sex again and, while she kept telling me not to leave, I left around 10:00.  We agreed not to tell anyone, so i've kept it a secret from my roommates.

Anyways, that was 2 nights ago, she joined us all for lunch on Saturday, I didn't say too much to her but that's my nature anyways, especially in groups. What I want to know is if all her cuddling and the morning sex would be signs that she'd be interested in doing something again.  

The thing is, she is a wild girl. I've always thought too crazy for me, but I actually enjoyed talking the morning after. I don't know what I want but I want to touch base with her so we can figure it out. What is your suggestion for best message to send her if I want to figure out what she wants / thinks of the night? I'd be interested in FWB sort of relationship, but would be open to the idea of getting to know her better / dating too. It could also be possible it was just a one night stand with her... 

*Didn't get her number but have her on facebook & tinder
<bot>: Hooked up with a girl and was surprised to find I enjoyed hanging out with her the morning after.  She was very affectionate the morning after. What is your suggestion for contacting her?
