Don’t overthink this one.
He really just doesn’t know.
Speaking from a male perspective, when I say ‘I don’t know,’ I mean it.
I have no clue.
If I did know, I would give an honest answer.
Of course, there are people who lie.
But if you try and dissect it too much, you’ll go insane thinking of all the possibilities.
Instead, assume he doesn’t know the answer.
It’s more likely than not he truly doesn’t know.
