This is a great opportunity for him to learn what life will be like if he keeps going down this path. If he's scared then he's learning something so be very thankful for that. I would be more scared if he wasnt worried right now. One night on the streets might be the wakeup call that he needs. The rehab is doing this for a reason and if the night is too easy on him what will he learn - if he finds a cozy bed to sleep in then he may not get the lesson that he needs to learn. I hope that your weekend is peaceful and that you find strength that he is in the hands of HP - I dont mean to sound cold but it may be best if his weekend is worrysome and scary be thankful that he is smart enough to be afraid right now. i pray that HP gives him as much as he can handle and keep him safe while showing him what he needs to learn right now and that he gives you peace to trust this difficult step. You have lived with the fear of his addiction and now maybe its finally time for him to have some fear.
