Great post caliboy, and great response by Flow. Great to see you moving towards deeper inner work, and I've got to say it made me happy reading this.
I would point out this:
I thought i did everything right
That's where some of your frustration might lie - thinking that by feeling enough contentment with yourself will you make the right move to influence a girl to sleep with you. Maybe she really was busy. Maybe she was kind of "meh" on meeting up. Maybe she didn't want to tell you straight up that she didn't want to meet and kept pushing it off. Either way, it doesn't really make much difference as to the end result.
What matters is being able to feel the disappointment and not let it influence your actions (what you do and don't do). Lick your wounds and move on.
