for what it's worth, here's my new policy:
* try and be the one who initiates things, because if she's waiting for you to contact her and you're doing the same thing at the same time, that's just kind of a dumb stalemate that doesn't need to happen
* focus on getting as many options as you can at any one time, so if one girl bails on you then at least you can still see what Betty, Susie, and Veronica are up to
* if a girl gives you the cold shoulder then do your best to forget her permanently. don't be a dick, don't make a big deal about it, but just let her disappear like a fart in a windstorm because life is too short to hold grudges or pursue women who aren't ever going to reciprocate. put that time and energy into finding someone else.
