I've been on eharmony awhile now and finally started applying the techniques I've learned here and on other pua forums. I've done ok and # close about 20% of the girls I'm matched with.

I try to be cocky/funny on the phone, and I set up dates usually within the first or second call. But I'd say at least 1/3rd of the girls I'm supposed to meet up with flake the day before or the same day. The last time this happened, I was going to take a girl to karaoke and we agreed to meet at my house, but she flaked 2 hours before our date.

What do you do to stop flaking? (Almost all the girls I go out with are from eharmony btw.)
