Firstly I cringed very hard reading this, next time you don't have to be so descriptive.

I will give a soft ESH, since

1. You are just a boy, and even though you wanna do stuff, it's a bit difficult to respect boundaries that you are not sure exist.
2. The girl is either chatting shit to her friends or is pretty unsure about all this stuff and can't come outright and say it to you.

Either way I think it's best if you don't confront her about AND don't do anything. For the other two nights, don't come on to her or anything unless you are 10000% sure she wants to do stuff. Also I might be completely wrong, as the whole thing depends on your friendship dynamic (such as flirting and etc)
