Oh no, Kate, You poor thing. Hardly one son is grown and out of the house…and then the next one comes along with those teenage problems. I think what Laurel said is excellent advice about reading his emails and website. That way you are on top of things.

Does your son do any sports? My sons played ice hockey, and it was exactly that, that kept them off the streets. Just like with little children, you need to distract him and find interesting alternatives. See to it that he doesn't have much free time, and get him involved with other boys that want more in their lives than just 'hanging out'. So I agree, it's wise to forbid him further over-nights…but don't just ground him, find a substitute hobby/sport in a supervised club.

I surfed around a little and found this link. Looks like they may have some good advice for you.

Sounds like you are taking control. Good for you Kate!
