It's times like these I really value my family.
But amongst my friends I've seen so much of the yo-yo effect. Leaving home only to return.
I suppose, from a young(ish) person's perspective what I really wanted when; was my parents to stop being so nosy. I think by giving him his dues and space you are definately doing the right thing. Dont doubt yourself because he'll know if you are. Explain to 'mum' that she still has a boy, but that he's growing up now and that she needs to let him, however he chooses to do so. I wonder idly, if you could contact his girlfriend. Not sure on the exact scenario but if you become well acquainted with her, and I mean learn to like her, your boy might start to see things in a different light. My parents are using this ploy currently on my brother, and so far it's working. (Mind you my brother is a little older)
Use your leverage. If he does contact you for any reason offer him something unexpected. A chance to have a beer with you, or maybe even to go for a drive if he's got his L's. At that age, to be 'self-sufficient' like he wants to be he needs to be able to drive. Helping him achieve his goals might up your chances of helping at least guide his footsteps.
Talk to her parents if they're available. And see what you can do together. I'm sure they're probably just as worried as you are.
Good luck. You'll need it.
