I recently met someone on a Meetup. We talked a bit and had few things in common. She exchanged insta when I asked for mobile number. We talked a bit and I invited her to play badminton. It was good. Now we are going to bachata social. She is brining her friends as well. As per plan we meet, I drive us(me, her, her friends) and we get dinner before the class and the social. I was able to get her to meet me 15 mins before her friends come and we drive for dinner. Now, I want to ask her for a date before it's too late(we met on Sunday, went to play badminton on Wednesday and bachchta social is on Friday) and she seems me just as a friend. I haven't dated in 10 years (i am 28 years now), so very much out of game. I am also bad at flirting but still want to ask her out. How do I make full use of those 15 mins to ask her out on a date?
