You lost the right to expect or demand a financial accounting when you and the mother chose to go your seperate ways. The child support you pay is reimbursement to Mom for the money she put out to support y'all's child. She can do anydangthing she pleases with the money.The mother of my second child informs me where my money is going and how much we will have to spend on this and that (given we are still in a relationship).
You purposely omitted the part that Mom works 'til midnight. You purposely skewed your original post (and multiple subsequent ones) to leave the impression that GM was staying with your daughter for a very brief amount of time. So, stop acting so outraged at Mom's 'lies'.
