You will never know until your son becomes of adult age.
Although I was not home schooled or driven anywhere by my parents, being with adults all the time was not healthy for me. Added to that, both parents were alcoholics as were their spouses. I was forced to be emeshed in their issues, they only time I escaped from the toxic enviorment was when I was in school, I then, had my own life and was allowed to think for myself, navigate myself through classes and deal with peer issues. Due to your home schooling him, he is shielded from that interaction, from that freedom.
He is 14, might be time to consider cutting the apron strings and let go of a little of that control
that you so embrace. He soon will be of adult age, are you preparing him for that transition?
Just my thoughts, if I am out of line, I apologize in advance.
