I assume, possibly wrongly, that at 23 your son has a job. If not he can apply for assistance or stay at a shelter or couch surf. It is amazing to most of us how resourceful our adult kids are when it comes to eating, sleeping and surviving on the streets. Many wont come home unless all rules are suspended. In other words they rather live in the streets than quit smoking pot or follow our limits on curfew, rent, or physical violence.
To me physical violence is totally unacceptable in my home under my roof. There is no excuse for it. You cant stay here and punch somebody else who lives here. Did you call the police?
We cope in different ways. Therapy is good for many of us. Al Anon is good if it applies. Self help books and youtube can help....I personally prefer a live neutral third party over doing it myself. A real person can provide comfort and wisdom a distant approach. We are too involved in our own problems.
Light and love!
