TM,
If the school administrator is aware of your situation, they should be more than willing to work it out w/you. Your wife is trying to control you and the situation. Stick to your boundaries and continue doing what you are doing. If you can pay the school directly, then do so. Also, by doing so, you have proof of the payments for tax purposes.

Take a deep breath and do not allow her to get under your skin.


Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
