I feel like I'm often too available, but if I act busy and with an abundance mentality (i.e. not asking more than once for a date, taking hours to reply) girls just forget about me most of the time.

Texting only for logistics doesn't work either. I set up a date in 7 days, go no contact up until 1 day prior and they flake even though they were interested in me and easily agreed to meeting up.
