My ex insisted on putting college costs into the divorce agreement. Both lawyers actually advised us not to do this but he was insistent, as if he thought I wouldn't pay my share. In the end, I was so glad it was there, as I don't think I could have relied on him for anything otherwise.
As it is, if youngest son ever decides to return to college I doubt Ex will contribute as he will be over the age limit set in the agreement . I will probably delay my retirement to help him.
And yes, even with alimony ( which expires in a year) my ex takes home twice what I do, AND his wife works, he has a nice mid-six-figure income yet is always squawking like he's poor.!
