You need to get him out of there! Money wouldn't be enough for me! The things he does are rude and disgusting! Tell your friend you can't stand another minute and she needs to move him in with her so she can see what it's like.
Your friend doesn't seem like the brightest crayon in the box either. SHE'S going to pay for that loser to say at your place?!
I'd have his stuff in trash bags on the front lawn. He doesn't need to be there anymore! He should be staying with your friend whose going through a divorce - she likes him - let him live with her. No one is mean to my cats or my bird - period.
