I'm fairly new to r/seduction. I went out with a meetup group for a wine tasting at a local restaurant. While we were at the table there were two attractive women at the tasting booth. The one wasnt pouring, who I will call M. She started explaining some of the wines history to me. I got both women in a conversation with me. I went in with no true agenda outside of having a conversation and drinking. M and I started talking more as I drank. I was asking most of the questions and then suddenly she started asking me questions. I took this as her starting to put her guard down. A new group of people had come to the table and I realized she had a job to do and my friends were leaving the table. So I asked when she was done and she told me. So I pointed over to the table and said when you are done, come over and lets finish our conversation and she said "ok" with a smile. I was talking with my friends and I see her walking out. So I call out to her. She stopped and I said were you going to leave without saying goodbye. She said she had to go and I said well let me get your number and she told me she wasnt interested in dating right now. Then gave me her business card. I said okay, have a great night.

I know I made some mistakes in the interaction. How can I improve?
