tell your husband how you feel, or depending on your relationship with your step daughter, talk to her to find out how long she is staying. By the sounds of it, she is rolling in dough. No bills, no car, no expenses really. Try getting her to pay your son some gas money if she doesnt get her on vehicle. Maybe try getting her to go look at apatments with you. I mean im not the best with family advice, but I'm 20 years old and have lived on my own since I was 16, and never once askd my parents for a dime. But do what you think the best way to go about this is.
