Hey guys, so today I went up to a girl when she was alone and said to her that I find her cute and if she wanted to hang out all in a less in a minute. She was slow to reply, gave me her number and said she was feeling unwell today. I gave her a missed call right after and said thats my number.

So question is, should I send her a text today saying it was nice meeting you or should I just text her a day after saying lets meet up and keeping in mind the abundance mentality? (Probably going with the latter)

Should I text first casually or first meet her/bump into her or should I just say meet me at x place on the weekends. Any possibility to minimize the flakes and maximize the k-close on a first date ?
