Hey, I need some advice.
My sister has had problems with work, so, my dad and I have been helping her with money. She has a new job now, but, it doesn't pay enough for her to live the way she is used to.
My only advise would be "Be careful". I had a friend who helped out his sister by cosigning a loan. Needless to say she ran off with the car and didn't pay any bills. My friend didn't find out what was going on until collectors came-a-callin'.
His credit was wrecked. As luck would have it his car was stolen after that, insurance really only paid the original off, then he couldn't get another car to get to work.
Things spiraled out of control and 7 years later he's still not back to the standard of living he had before ....
In summary don't let someone that's drowning pull you under also.

I'm not sure about cutting the person off cold turkey but I'd be all for laying out some harsh ground rules like forcing the person to live within their means and things of that nature. If things don't start improving then you it may be best to cut the person off esp. if their character isn't that great anyway.....
