In general, what should be your attitude towards women who are "flaky" - by that I mean cancelling dates, not always responding to messages, etc. Should the attitude be indifference, anger, call her out as a flake, dump her immediately? What?

Here is what happened to me:

Met a girl, we went on a date. Things went well, I had a good time and I think she did. I invited her back to my place, we had some more drinks and made out a bit (all good so far!) but she kind of resisted going further so I didn't push it. We agreed to do something again the upcoming Saturday.

Friday I call her to confirm the details. She sounds a bit unethusiastic, but she agrees, so whatever. 20 minutes later I get a text saying she has been called into work and the date is off. I just text her back saying "that's fine, I have other things I can do instead, talk to you later."

Since then communication has hit the rails, and I honestly think it's over. Thinking back, this may have been the moment it all went wrong. Maybe I'm over thinking this, but I'm starting think that I should have "faked" being mad about her cancelling on me. Let her sweat over it for a day or something.

I don't think women really respect "easy going" behavior. Thoughts?
