Step Daughter problems (need advise)

Take the car back, if she still has one. I'm guessing you probably also pay for her gas and insurance since she doesn't have a job. I know it's tough being a step parent in this situation. I went through it with my step daughter, and my wife was the enabler, no matter how much I tried to take privileges away and try to hold her accountable, my wife always gave in to her. It was when my wife finally started seeing things my way (almost) that she finally got off her butt, got THREE jobs and an apartment. She eventually had enough of the 3 part time dead-end jobs and joined the Army.

I posted an almost identical thread about her about 2 years ago.
