My ex refuses to pay his share for what he considers to be “extras” for our kids, including after school activities, field trips, and school supplies.

C – ex refuses to pay his share
T – what a cheap s.o.b.
F – pissed off
A – try to argue my point that he should pay for these things
R – no success, no money

Can you please offer me some new thoughts that don’t make me want to badmouth him to our kids? I’m biting my tongue.

Thank you.
