This is a good post.

I agree that it is readily possible to be emotionally-distant from a situation, such as this man and his wife.

I would call this a case of (likely) understanding your question, and (still) not replying with the data you're obviously seeking, making this a lie.

That said, if you want a specific answer, it helps to ask a specific question.

This would concern me, perhaps enough not to meet the person. But, if you can keep calm and dispassionate about him enough to gather other data, and have not other possible partners at the moment, it may be worth the time.
