Sorry for the long winded story (also if this is the wrong subreddit to post this on), but I am confused and know that I messed up in many ways. I wasn't initially trying to seduce anyone.

So I was at the bar with some friends. There's this one girl in the group that for awhile I have thought was very attractive. I don't know her but have been in her company once or twice before. I was having a great time, mingling and you know; put back a few drinks. I have heard that this girl is a kinda complicated when it comes to attraction. So I kind of wrote her off for the night. She made minimal eye contact with me throughout the night. But then a little bit before last call, people were kind of winding down and she decides to come over and talk with me/quiz me with some board game cards that were on the table. I understood that this was flirtatious in some way (I am not very socially apt in things like seduction and have never really tried to make advances on girls), and it was fun. Then as we were walking out, my friend came up to me and said that she was definitely into me and that I should try to make a move. I kinda laughed because I had no idea what to do. (I recently have kind of cleaned up my appearance; I have never considered myself attractive)

I decided I was gonna give it a try (though a feeble attempt). When we were walking, she mentioned that she was hungry for pizza and fortunately there was a 25 hour pizza place a block away; not to mention that my apartment is across the street from the pizza place. So I kind spoke up and said that I would go with her to get pizza. The rest of our friends headed out and so I thought it was a perfect chance! I bought her a slice of pizza and as we walked away, she asked me where I live and I said "right there haha." I invited her to come and eat with me at my place but she somehow avoided the comment and said something like, "Oh ok well are you going that way? I live over this way." and I said uh yeah I guess. and she said alright well see you later and we hugged and went our separate ways. haha i'm such an idiot, I didn't even think to ask her for her number.

But now confusion.
