Are these IOI's or am I friend zoned?

This girl who one of my best friends used to date and I have been hitting it off recently at parties (We move in the same social circle). Anyway I've known her for 4 years but we were never that close, but we would occasionally joke around when we saw each other. Over the past two weeks she has started to text me to see what me and my friends were doing during the weekend. We don't end up hanging out 1 on 1 but usually ended up at the same party. Last weekend I stepped up the physical escalation, guided her with my hand on her lower back, played with her hair even picked her up at one point while poking fun at our other friend's parent wedding photo(we struck the same pose as the parents). Now I would normally take this to mean that she was interested in me but in between all of this she is telling me how my friend used to cheat on her and still tries to call her. She then states that she has never and would never cheat on a boyfriend. She followed my leadership for the whole night but those comments threw me off and I didn't close. I'm just looking on some perspective on whether you guys think I'm firmly in the friend zone or if I have a chance? Thanks.
