what is this girl thinking? does she want something serious or just a casual fling?

a girl im currently VERY interested in, is playing with my mind. both of us have been very busy with midterms / other projects for college (we go to different colleges, shes in boston, im just outside about 30 minutes north) and we have gone out 2 times, known each other for about 3 and a half weeks. First night we went out, had an amazing time, ended up back at her place fooling around, ended up having some oral fun, and we cuddled / she wrapped my arms around her as we fell asleep. Second time (2 weeks after that) we went out again, again had an amazing time, again ended up back at her dorm, this time it lead to sex, and me making her feel 'the best ive felt in years', which included her pulling me against her at multiple points when she got close to cumming and telling me to hold her.

But whenever we aren't hanging out, we have limited to no texting / talking online which i don't mind, in person she always likes holding my hand in public, putting her head on my shoulder, cute **** like that. She has also cancelled plans with family to hang out with me on both occasions, to the point where her dad called last time we were hanging out to tell her that she NEEDED to hang out with her family, but she still canceled plans to be with me.

So what do you think she wants? best answer gets the points.
