What are some good recommendations, suggestions, techniques or tactics you might have regarding flakes?

Quick scenario, I'm getting IOIís from this girl and I know sheís into me just by her vibe. She agreed to meet up with me, but cancels last minute? I donít understand why she would agree and then just decide not to go?

Flaking is a sticking point I'm currently working on; I just canít get a girl to be committed to meeting up and being serious about the date. What can I do for her to show up and not cancel?

Please give me your best advice, Iíd really appreciate it, thanks!
