A back story, I'll try to be brief. She got cheated on by her BF of 7 years 9 months ago and ran into my arms. I was genuinely her friend before that so we hung out and things got really datey - dinners, walks, museums, etc. I fell for her (foolish but emotions aren't subject to logic). She, still distraught from the breakup moved to a different city to with the pretext of 'taking some classes'. I had reason to be there some soon after she moved and things seemed just a intense, lots of touching, eye contact, continued date activities and nearly continuous texting when we were apart.
Over the summer we didn't see each other much and texting dropped off a lot. This fall I had a work project there that required my presence one day a week for a month and a half. She made time in her schedule (80 hours a week between classes and jobs) most of the times I was down there and each time we hung out for several hours, going to dinners, going on walks etc. Some weeks she seemed to be very into me and other's she was more withdrawn.
On the last weekend I was down there I asked her out. I should have done this earlier, when I first started falling for her and when she was showing strong signals but I justified that I didn't want to take advantage of her when she was on the rebound (really, it was at least 1/2 cowardice). Anyway, she didn't immediately say yes or no. Later, after I had left, she texted me that it wasn't a good idea for us to date but that we should keep it friends. I texted her basically ok but was really disappointed and haven't contacted her in any way since. I saw her once over thanksgiving at a bar and we talked some, if somewhat awkwardly.
Last week she texted me about the name of a place we had gone and tonight she sort of asked if she could go skiing with me tomorrow (she asked for a ride to the resort and given our history, in the past this means we'll end up skiing together).
To my understanding, this might be progressing well for getting out of the friend zone. I cut off contact and have been doing my own stuff. Now she is chasing after my attention with no promoting from me. The question is how do I act now when we hang out? Do I remain friendly but cool? I need some advice on where I go from here.
