My 15 year old step daughter has a severe attitude and rudness problem, they say kids are acting there teen lives. i know they can be difficult but i cant abide by rudness. i took 4 step children in four years ago now, and things seem to be going from bad to worse with the step daughter. she was never close to her mother and always relied on maids and nannies to take care of the children. after her mum got sick i took her in and gave her all the love support i could ever give to any child. she never tries to call her mum and even when she does there are no emotions there at all. she is very rude and doesnt accept me telling her anything. she is only nice when she wants something, other wise she is pre occupied on her lap top and tv, chatting to friends and is always wanting to go out with her friends and doesnt like anyone coming over to see her.

She has realy started to get on my nerves now, i keep trying to say she is only young and needs support, and then i get the ruddness and attitude again. her father says i dont know how to deal with her, but i think i have tried every approach, and am thinking to ignore her completly now is the only way i can deal with this. it also doesnt feel good living in an unhealthy atmosphere in the house. How do I approach this.............
