Could it be the green monster...jealousy? (is that a green monster..hmmm) Anyway, I've had those kind of conversations with my h too and it's usually because they truly WANT to know who you are with, if there is someone else...h is lonely for you.
You got him thinking. Let him think some more by not giving into answering his why questions. Say, oop there's the boss got to go or my other line is ringing got to go!
It's not productive anyway to answer his why's, is it? What did it get you? Next time find a way to end the call...throw him for a loop.
