Online date cancels on me 17 mins before we're supposed to meet

[Reason]

By "family problems" he likely means "My wife found my online dating account"

Don't bother I think. First impressions matter, and he blew his.

My, you've had a lot of dating questions in short order. I don't know that we're the right board for potential relationship advice, since we tend to focus on the etiquette of situations.

Etiquette-wise, he was rude if he was jerking you around, but polite to let you know he couldn't make it instead of just standing you up. You would be completely fine either pursuing him or not. Your call.
