It’s a difficult situation on so many levels. The kids should get money from the parent but it’s difficult to make sure that it goes to the kid and not funding something foolish on the mother.

Just make sure not to be a dead beat. There’s a difference between that and a dad who is trying for their kids. Don’t let the ex wife ruin your situation with the kids, because in 10, 15, 20 years you will regret it.
