Right so 2-3 weeks before, I met this girl for the first time and we talked for about 30 minutes with mild flirting I guess but no numbers were exchanged, the second time I met her recently on a night out again and she approached me and mentioned to me how she wanted to talk to me again and we flirted quite a bit with a lot of touching etc and then exchanged numbers just before she had to leave with her friend but she gave out massive indicators of interest throughout the night. I said to her I would text her some point soon so be ready, still seemed super interested, so I messaged her the following evening saying "Hope you are ready " and got no response at all 24 hours later which seems amazing to me with all the interest shown I expected a response very quickly.
What's the next step, wait a bit longer, message again when I am next out maybe asking if she is out or should I just forget about her now and on to the next girl?
