Why did I get ghosted?

But another lesson... and this is something it sounds like you and I share ... is we have to be VERY careful NOT to get overly invested in a 'relationship' too quickly. There has to be a more or less equal exchange of attraction, interest, openness, and so on.

That's exactly the dilemma. It was exactly that, or so I thought when he volunteered to invite me to his place. As far as I know, in real life, that means one enjoyed the date. So I'm left thinking he had an abrupt change of heart over the weekend, or I did something egregiously wrong that I don't know about (and he didn't make known) while I was at his place.
