Oh my Thumper, I feel you on this one.
My nearly grown kids, my youngest especially has to say,
"Mom, it will be fiiiiiiiiiiiine."
LOL
So, Thumper, it will be fine.
Could you go for a little while, and then take the 4 year olds home?
No need to hang out with the ex, football fields are pretty big.
Just a thought.
