Replying to Leaving the Friendzone

I've recently decided that I'd like to leave the friendzone with a girl I've been good friends with since my freshman year in college. I'm now in the final semester of my senior year.

Ran into her at the bar the first Thursday back from break, and she invited herself over for dinner that Sunday. We made dinner together then watched Silver Linings Playbook.

Shared a blanket but didn't cuddle. Walked her out but didn't kiss her. Pussed out, maybe... do I have the green light to make moves or is she just being nice?
