((meadowsis)) - I know of several people, here, that have had a similar list - meetings, shelters, sober-living, etc. If he tries to convince you he has nowhere to go, he needs to stay with you, etc., I would simply hand him the list and tell him something like "you may want to check out these options" then let it go.
Keep taking care of YOU, the rest of the family can take care of themselves.
Hugs and prayers,
Amy
