19 year old college kid in the UK here. I've never used to be so interested in getting with girls but about a year ago, I decided I would stop hiding at home and playing video games and actually improve myself as a person by finding some hobbies

That was a little preface. I went to a club today, and I know all this shit goes out the window because you can't hear yourself in clubs. I don't actively "hunt" girls as some of my mates seem to love doing. I try and focus on having fun and I assume it would come. Got the closest I ever have to kissing a girl today. I started dancing like crazy, offbeat doing any move that came to my mind. I caught this girl's eye contact so I moved over to her and grabbed her hand over to dance with me. Eventually, she started grinding and I suppose this the point where I'm supposed to grab her in go for the kiss. Didn't do that, and just kept stalling and dancing with her. Eventually she lost interest and just moved off with her friend. I'm not sure I was outright rejected, since she seemed to respond to my advances fairly well. What could I have done better in this situation. How do I stop stalling? Did end up adding her on facebook, but that doesn't amount to much?
