I want to strike the right note between detachment, validation, and "no". I'm thinking something along the lines of "This was your decision to get divorced, your decision to stop working on our marriage, your decision to move into another house, your decision to buy a dog and two cats so you had to hire a pet sitter when you went to work. I'm sorry you find yourself in financial difficulty. It must be very hard for you. But it's no longer my responsibility to fund your lifestyle. After the child support ends, I'll be happy to pay half for things like new clothes if you provide me with the receipt."
Thoughts?
Keep it simple. Just say, "After child support ends, I'll support my children as I see it being appropriate when the time comes" or something similar. All the other stuff you want to say, just drop. It shows resentment, it is you trying to get her back, and doesn't help any relationship. It won't change anything for you.
They are your children, and I assume you want to see them succeed in life, etc.
