I have been married to my wife for a year now and she, her now 17 year old daughter, and I, live together.
My stepdaughter has known me since she was 14, and has increasingly acted aloof, distant, and rude...and not just to me, but to her mother, other adults, and peers. Her father has her about 40%, and provides little to no leadership or examples of good parenting. She does little or nothing to help in our household, and my wife feels powerless to direct her doughter or require any speicifc rules or tasts, becuase..."her father will just do what he wants when she is with him..."
I have gone out of my way to be firm, supportive, and always available to my step-daughter for anything...which amounts to a lot of chauffering (!). She now is driving and has 'finessed' her mother into buying a car for her, (yes, I 'loaned' her mother the money), and voila! ...the stepdaughter/princess now announces that she is having sex with her boyfriend, which is unacceptable to me (along with her attitudes, rude remarks, and 'all for me' attitude.. What truly is unacceptable though, is the way she treats her mother. She is a user of people, and a young, conniving teen girl in the worst sense of the word. Her mother still feels powerless.
Can anyone out there help me with advice?
