No, I don't think you did the right thing.
Is your wife not allowed to date others unless you've known them for years?
That's not a reasonable position.
I disagree with the people who say your instincts were right because the guy disappeared. If I was expected to immediately meet the spouse of someone I've known for a week and been on two dates with, I would freak out and disappear too.
Maybe the guy was worried you & your wife wanted a sudden threesome or something. There are many reasons why he could have disappeared.
Single, straight, female, solo, non-monogamous.
