I met a girl at new years eve, can anyone help me?

Hey all, its about 8.20 in the morning here(got home around 7.50). Anyway, i was at this new years party at my friends house, which started at around 1.00 in the morning. Anyway to make it short, a guy(who kept calling me bro, probably because i bought cigars w. him, also nearly got in a fight with a another dude) was constantly hitting on a girl, who didnt like it. Now, i was pretty tired as it was nearly 6 in the morning, so i was laying the couch beneath the stereo. Anyway, when this girl he was hitting on went to change music, then i said something like "hey, nice cleavage"(Really good cleavage, changed music constantly afterwards) and we got talking shortly(she didnt mind, i even told her that she should just tell me if it bothered her that i looked). Anyway after about 5-10 minutes, she then sat beside me in the couch put her head on my leg, and we kinda held hands for like 2 hours while chatting. Anyway, I think she is really pretty and a cool person, so should i try to do something about it? For the record, then ive never met her before, and neither of us were drunk or anything. The only reason the party kinda ended was because the host turned on the lights(dark room, closed door, "romantic"/"girly" music) and turned off the music and asked us to leave.

So, what do you think?
