Teenagers - aren't they great

My DD is nearly 15, she has set chores for which she gets paid and has to budget as most things she wants (not needs) she has to pay for, but she still "forgets" to do her chores, I dock her pocket money...

Being scared that one day she will want to live with her dad is always in the back of my mind to, she hasn't spoken to or seen him in 5 years, her choice, but the thought that if she gets peed off with me enough that she might want to go there is still in my mind, thing is never let them know that that is a fear you have, just gives them amunition (sp) iykwim.

I think that kids at this stage (12-15) and I guess some younger ones and older ones just want to test how far they can push it and want to assert themselves. I would say just stay firm and enforce your rules, you are doing nothing wrong.

My DD and I are best friends, she will talk to me about everything and tell me most things.

Just stick to your guns, she'll grow out of it soon enough
