In a word, NO. Let him find out what doing for himself when he moves will be like.
Don't pack his lunch or his clothes. Find something else to do when he goes. Make sure he knows he has no drop by, come over for dinner or TV privileges.
Think through the boundaries you need to set in order for him to understand the consequences of his choices.
It almost sounds like he is your older child who is testing the rules. I would think he is as conflicted and confused as you are but you seem to be much more aware of the impending realty of his choices. Hold him accountable.
The only easy day was yesterday
