Faith
I have been through the same thing in the past with my son. It's no picnic having them live at home, and my son knows that I love him but that he can no longer live here.
Like you son, mine didn't work, or he would pretend to look for a job and not find anything. Eventually I talked to him and told him he had to find something, or get welfare, and find his own place.
I put a time limit on it and helped him look for a place. He found a clean , nice room in a decent house not too far from where I live. He was welcome to come for dinner if he was hungry, but the rest I left up to him.
Doing that helps them to learn to look after themselves, and it gives us our peaceful homes back. They are grown men now, and it's time for them to learn to look after themselves, however humbly.
Sending you my hugs and prayers. I know that right now is probably a horror show and I promise you that it can get better.
