From Lillamy: I just want to add my "ditto"...
His family is just afraid that without you, they would have to step in and support him and bail him out, etc. It's much easier for them to dump the guilt on you and think "well, he has her taking care of him, so we don't need to bother."
And if it were me, I would say that straight to their face. With any luck, they'll be both indignant that you figured them out and embarassed enough to leave you alone about it.
But then again, I have a gland in my neck that secretes profanity when people irritate me, so......
