So I got a girl's number and texted her it was nice meeting her and we should go to the <a popular bar> "if she's free tomorrow (Sunday)". She said she was busy that day, but also wrote maybe next time. Could it mean she's interested to go on a date with me some other day? I replied with "no problem, let me know when you're free we can then go out". She didn't reply after that so far. Should I ask her out again for this weekend or let her message me first? Will I look too desperate if I message her first again? Thanks!
