23yo difficult child is going downhill after being stable for several months. He still has no job and is not in school, being content to spend his days in front of his easy child. He did something stupid, dangerous, and illegal this weekend. His brother's friends were involved in the incident at a party, and his brother ratted him out to me. difficult child is angry that I don't believe his side of the story, and as a result he is giving us the cold shoulder, stopped taking his medications, and said he doesn't plan on keeping his doctor appts. It's extremely difficult to ever get any information out of him (even his therapists have said so), so I don't know exactly what his thought processes are, but I feel like it's out of spite. He wants to punish us for calling him a liar and taking the car away, and the only way he knows to punish us is to make us worried and angry. I'm toast. Done. I told him that if he wants to continue down a path of self-destruction, he needs to hold his own hand because it's not fun and I'm not doing it anymore. If he doesn't get his head out of his ass, I *will* throw him out. This requires a 30-day written notice in my state. Call me soft, but I don't want to throw him out in the dead of winter. He really has no place to go. If it comes to this, do you think giving him until Spring is a bad idea? That's like, four months to get his together. Then, if he ends up on the streets, he will have the warmer months to acclimate. Thoughts?
