Hi Yvette,
You are not doing anything wrong!
We are both in the same boat - I divorced their dad 11 years ago!
My eldest daughter (14) does the same . I think its part of growing up and testing the waters and boundaries.
My 12 yo has not done it to me yet but I am waiting for it.

MSN - I hate it! I refuse to let them have internet access in their rooms cos I dont have control of what they do when they 'go to sleep'. I have it in the front room opposite my bedroom - so when Isay get off - they get off and cant get back on with out my knowledge.
Sarah(14) loves her little sis Emily (12) but they do have theie little tiffs - but at the end of the day if one of them is in trouble they are always there for each other.
Yes they do think we are slaves to them .............................I think that nothing you are going to say is going to change that thought. I have also tried talking to Sarah but it goes in one ear and out the other. Sarah also loves her little brother Kayne but everything else is a priority, where as Emily lives her life for him and youcan tell the difference in his behaviour to both of them.
Sarah does not go to her dads anymore - her choice after an argument they had over 1 year ago. This has caused Emily to feel sorry for him and she now spends a week with him and a week with us. THis is hard on us all. You should see Kaynes face when he picks Em up - it breaks my heart, kaynes heart and also Em's .

Just keep doing what you are doing - it sounds good to me.
This is a trying to time for everyone and as long as you can still communicate with her - you are doing good.
Thats what I find is great about Sarah - she talks to me and is honest and thats really important.

Sorry I rambled on and am all over the place. Just typing what I think when the thought hits me! #-o .

Good luck!
