I went out on a few dates with a very nice man from PofF. He wasn't for me.
I think, in general, many men flirt/email/phone, but when it comes to meeting a person in the flesh, they lack the testicular fortitude to have coffee with a stranger. That *continues* to be my experience. In this economy, he may be short on money, too. If he asked you out and didn't budget for it, then he's kind of flaky.
Actually I had an experience recently in which a man sent me messages that were sort of non sequiturs. I guessed that he was emailing several different women and wasn't keeping track of what he said, and to whom.
He ought to keep a clipboard by the computer, like I do.
I am cutting down on the time I spend emailing and phoning before I meet. Either a fellow is able and willing, or he's not. If he's not, and rather quickly, I cut my losses and move on.
Being "sick" and then having "family problems" the same evening would be a deal-breaker for me.
