Step Daughter problems (need advise)

Thanks for all the advise guys but we sat down with her and gave her the choice to stay home and do work around the house until she finds a full time job. No going out, no friends over ever, or go back to school full time and work part time. And if any thing comes up missing or anyone in the house when were not home, Her and all her **** will be set on the curb, and if she dont like these rules then its time for her to pack her **** and get the **** out. Told her its time to grow up and be responsible or pack her **** and and let her feet beat the street. Basically last chance to do the right thing and be respectful and give a **** about her family and our home or get the **** out.
So we'll see what happens I just hope for her sake she grows up because its awefully cold out on the streets of Chicago.
