You can't go completely dark on him while he's living under the same roof w/you. However, you can treat him as if he were a roommate and if he wants to talk, then listen and talk. If he doesn't want to talk, then leave him alone. Follow his lead. No more talks about seeking help or getting out. No more talks about being done and certainly no more talks about seeing a lawyer (especially this one, as it could come across as a threat to him).

Re-read the detachment thread and like I have suggested, read HaWho's threads. She's mastered the art of detachment and yes, she's learned how to deal w/her h while living under one roof. This is his problem to fix. However, you can make your home a safe spot for him, by giving him space.

You can reason w/someone who isn't willing to listen or is operating on pure emotions. If you get frustrated or angry, take a walk. If you need to speak to him, do so in a calm, level tone and look him n the eye.

Keep the focus on you and dig deeper for patience as you are dealing w/a teenager right now. No, the man you knew is gone for a while and in his place, is his younger self.

Here's the link to the Detachment thread:

Detachment

Detachment is for you so that you can find you footing once again and not to always react to what he says or does.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
