Me: BW, divorced, now fabulous and happy!
What does your divorce decree state about extra-curricular activities and payment? Is CS supposed to cover them all, or are they split in some fashion?
If he were a stand-up guy, of course he would pay. But if he were that guy, he never would have cheated, you'd still be married, and not in this situation.
You have to remember who you're dealing with!
Married: 11 years, no kids
Character is destiny
