She is rude to me, talks with a sneer in her voice to me almost all the time, is lazy and contributes nothing to the house (cleaning, cooking, tidying up etc) and if I ask her to she says "it's not my bloody mess" or something similar.
My own 3 children (all 4 live with us, 2 of them are her half siblings, 1 a step sibling, she is the eldest) do not speak to her father (or me) that way. I have tried speaking to her father, my dh of 10 yrs, that I find her attitude unacceptable but he invariably lets her off the hook and she has never apologised to me.
I am the main breadwinner in the house, and fund a horse for her, arranged her prom dress with her, pay for her holidays, organised birthday parties, baked cakes etc etc. I don't mind doing this as we are very lucky to be able to afford it, and the other children get similar perks - I have literally treated her as one of my own for 10 years. In a recent argument I said something along the lines of "as your parents we don't think you should stay out so late" and she spat back "YOU are NOT my parent".
I have spoken to my dh this evening that I am not prepared to keep shelling out for her if she is going to a) behave like a spoilt brat and b) speak to me with such disrespect. Now she is earning she can start paying an appropriate ( to her meagre earnings) contribution toward her horse. He is now in a huff and barely speaking to me.
I know teenagers are a general pain in the proverbial, but.... AIBU?
