This is my first post on here; so I request you guys to go easy on me if I don't use the technical PUA slangs in any context.

I [23M] met this girl [22F] outside a club after the main DJ's act got over. The club was almost closing for the day. We were both standing by the entrance waiting for our friends. She had an unlit cigarette in her hand and I was just standing at a corner smoking my juul (trying to quit cigs). I don't know why she thought I had a lighter but she came up to me and asked me for a light. I told her I did not have one since I have been trying to quit smoking cigarettes.

Somehow we got started talking and I came to know that she was from out of state, visiting one of her friends and was going to leave town in 2 days.

During the conversation, I could sense her being playfully "touchy". We even had another guy join the conversation, when he was actively trying to hit on her by offering her free drugs and complementing her the whole time. I kept quiet and just sat down beside her. She did not pay much attention to the guy after accepting the free drugs and just kept replying to everything that I was asking.

Somewhere during that conversation, she asked me where I lived in the area; so I told her my apartment's name. After a while, she was trying to take drive her drunk friend home so we left that outside-club area and started walking towards where she had parked the car. I asked her where she was going and she jokingly said, "What about {My Apartment's name]? Hahaha". I laughed with her and we just kept walking. This is the part that got me thinking later. You see, I was pretty drunk too and I could not even think about inviting her over (even if I meant it jokingly). Plus I was scared it was going to creep her out a little if I asked for a kiss or just to come to a stranger's house that she met an hour ago.

At the end of the walk we hugged and then I hugged her friend but I could tell they were two different kinds of hugs. One was a side hug and the other one was NOT. I told her I would like to see her before she left; that is within the next two days. She said she would be back in my hometown a month later to see another DJ.

Maybe I blew the chance to make any moves since I did not make a move on that particular night at that particular instant. Remember, that we were strangers an hour ago all of this happened.

I texted her on snapchat the day after but got one response after waiting for hours. She hasn't even opened my second text and is going to leave tomorrow.

Could you guys please help me assess this situation and help me learn something from this experience?

TLDR: Met a girl outside a club, sensed some flirting but did not make a move. Please help me learn something for future references and help me stop overthinking about this.
