You really need to dig up those papers. If you were not ordered to pay this 2k in divorce court then it needs to stop. You need to see what was actually ordered to be paid.
The last thing you need is for her to come back and take you to court because she is spending it all and then wants more. Then the courts see you have been doing something that was not ordered and bang why not squeeze you for more. I know it's not usually how things work but man 2k on top of 250k is just nuts. Get your paperwork and start reading it over and over.
