I tried just setting dates with not much talking, tried sending some fun texts regarding a joke we had and so on and so forth... Thing is that I get flaked last minute quite a bit, out of 4 numbers got 3 to flake, and that's just in the last 2 weeks.

What's the right way to do it?

Thanks

Edit - important to say, I set these dates 2 days ahead max. Edit 2 - They are from online apps
