Well hugs to you, because I think you really need some!
The hardest thing for us to do, is to let them go, and to trust that their H.P. has a plan for them apart from our enabling.
When you have had enough, and have hit your bottom, you will find a way for him to move out, and on with HIS life.
Regardless if it is an intervention, or giving him a time limit to leave, and calling the police.
Hugs to you, I know how hard it is.
