First you have to acknowledge the fact that you and your spouse taught her to be this way. You DO own a responsibility here. The first time she dropped out of school was a "shame on her" the second time was a "shame on YOU."  She has learned that she does not have to be responsible for her maintenance and upkeep, that you will take care of her.
As an adult she is free to move where ever she wants, and it looks like she wants to be near you. I would first have a heart to heart with your spouse. You do your SD no favors by arresting her adult developement this way. What would happen to her if you both died in a car wreck or something and she had to pay off the debts? After discussing your position with your spouse, and coming to a joint plan of action about how to handle future hand-outs, I would discuss things with the stepdaughter. As in my above response, she may think you're horrible and tight-fisted, but sick to your guns. In the long run you, and she, will be much happier knowing she is able to take care of herself.

but I don't think you can make her not move close to you but you can control giving her any financial help.  Sounds like she need to be cut off completely financially.  See my post below as to my feeling about dealing with adult step children.  But you and your husband should come to a clear agreement about the no more financial support issue.
