Thanks everyone, she's definately not getting any of my money anymore unless I know its going towards a good cause (i.e. groceries, etc.)

I don't know why she does this to me. I try so hard to make her happy. I get straight-A's most of the time, with the occasional B, I drive, I have a well paying job, I never ask her for money, I am responsible and I take care of children well, I'm honest, trustworthy, have never drank or smoked anything unlike 80% of the kids my age... I DO NOT want to drink, smoke, do drugs or any of that... I have no desire to do stupid crap like that. But I still can't make her happy.
