There an age range where almost everything MAY BE confusing.
But something is probably true: they need more peir acceptance and place among them than perent´s words.
Be open to listen to him, but don´t force a talk.
Support his choices but know that some of them are still in the future.
And that a affectionate but not overacted care and stable emotional enviroment will do more than what talking about what he still have no words for (or, at least, not now with his mother) may help.
Years ago, I had to deal with learning to be the father of three girls, with not available mother´s role.
Not the same, not easy, but feasable.
Courage.
