I agree, except for the "BF giving a good fark"... that'll be
too good for you.
Stop thinking about ME, MY and MINE!
Stop thinking about yourself for a freaking moment and realize that
she's your family.
Maybe the reason she takes/uses your things is that she looks up to
you and wants to be you (God forbid if she only know the truth, the
person you really are!!)
Maybe you need to reflect on your self-centredness
Best wishes.
