Yeah other people are right, if you'd DTD he very likely wouldn't have contacted you again and you'd feel worse. And 'good luck in your search' means goodbye. Sorry,
This often happens, you meet someone online and think they're great, meet them in person and they don't match up to your expectation in some way. Shorter, smelly, dull, or in this case just a bloke who's looking for a shag.
So, MrMotor wasn't the same person you thought he was (as if he was, he wouldn't have been a dick) - so you're not actually comparing MrIT to the man you met the other day, you're comparing him to who you thought MrMotor was.
MrMotor wasn't right for you because he's just looking for a shag. MrIT isn't right for you either (although maybe he could grow on you)
You're not being weird. Your twat radar is working pretty well.
