Step Daughter problems (need advise)

Well start with making her get and keep a job if she wants a roof over her head. Your wife whats her role in all this? Once she starts making money. Make her pay rent maybe not alot but enough to make her know she has to pay her way. Keep that money (if your not hard up for it) save it for her till she gets 3 months rent and then "set her up in an apartment"
