First thing you need to consider is not talking to his friends about him
and what he says / does for you own peace of mind.
Have you lined up a place to move when parents buy you out?
Sometimes proactive steps like purging you possessions, packing,
and getting ready to move on can speed the healing process.
Quite frankly from what you've posted, he may never choose to quit
or even admit he has a real problem.
You are very smart not to have brought an innocent child into this.
The book you bought is excellent--check out our Friends and Family forum
if you want to talk to others who have been right where you are now.
