You're right. He's in the right place.
Just like when they were little, and they didn't want to get a vaccine or say sorry for hitting their sister, you have to continue to be the parent he needs, not the parent he wants.
Things change. Healthy young people may need financial help through college, some tutoring when they're struggling in a class, help with their resume, an ear when they experience their first broken heart. All of which we would gladly provide.
But our struggling kids needs different things .... a reality check, rock bottom, professional help. Feel confident that you are loving him when you're helping him with those things. You're giving him the best chance at health and maturity.
