Question about a girl I like?

Well I realised after the weekend that i like this girl I forgot about and we used to see eachother but then we stopped because of past commitments like uni and so on!! But now she has a bf and she told me even though I have a bf we can still be close lol confusing yes!! Anyway I met up with her this week as friends at a nightclub, I had so much fun with her and we were really close that night everyone kept asking are use bf and gf and we would both awkwardly answer no!! And she was dancing with me n hanging with me all night!! Even kissed me on the cheek like a gf would. She also gave this girl a greasy when she tried to grind on me and went into the toilets with her friend!! So after that night I couldn't stop thinking about her, So the question is does she still like me? And I know I don't want to break up her relationship but I feel one day if we r alone stuff will go down so should I confront her?
