I dont know about u but I work damn hard for 600 dollars I would press charges on him and let him know that its unacceptable to do that to u.. As an addict he WILL not not die out there he will survive just like he did the last time he was out of your home. He knows that pneumonia card and he will play it till the end will u call his bluff???? He wont die in the cold addicts are resourcful when it comes to a place to stay, no need to give him a soft landing he has to the tools and he knows the tools to get clean again. Then again why should he, he has a warm bed, food, clean clothes, whatever he wants right now hell I wouldnt get clean either. Set your boundries press charges whatever your motives are at least he will kknow its unacceptable to STEAL from your parents...
