In a letter to Joe Ludwig Blake Abbott wrote:
"I know my CSA payments are spent on Alcohol, Nicotine and what ever else the ex needs. WHY? Because your system allows her to do it! Again, make those in receipt of CSA payments account for the money and I guarantee you would almost wipe out your outstanding debt. If every paying parent got proof the money they have to pay was actually being used for the children.... you would be on your way to having a much "fairer" system and you take away the receiving parents ability to hold the other to ransom."
Blake it's not your money. How your ex spends it after looking after the children is her business not yours. Get over the control issues. I can see why you are not married anymore.
