In a sitch like this, I like to ask myself, "What would Ellie do?"
You have a knack for seeing through the clutter and getting at the core of a problem. I agree that communication will be the key to letting this play out. S19 must understand that he is in a sitch where the law has an opinion. The girl must understand that sometimes asking for help means first acknowledging to those closest to us that we need help. Her parents need to understand how much she needs the help.
And you can only do so much. Let S19 know where you stand. Offer to help his gf if you can clear it with her parents. And remember where your responsibility ends.
And welcome back!
Thanks,
Joe
