Jeff,
Further addressing your own question, rather than the tangents which are erupting on this thread:
In hindsight I think I was a little hasty in my departure.
You weren't hasty. Don't torture yourself unnecessarily.
You had the information, and the knowledge of your own circumstances at the time, relevant to make a difficult decision. You did so and stuck with it, in spite of it involving turning down an attractive opportunity.
All I can say is, bravo! You sound like a responsible adult who is in charge of his own life, and can make a hard decision. That's good pilot material. There is nothing to fear about mentioning this in future interviews.
I confidently predict at more than one point in your career someone who took the alternative route which was open to you will whisper "wish I'd done the same as you".
Good luck.
