That makes sense. The kids might miss him that night, but if things aren't going well it might get them used to the idea.
I bought some small exercise equipment for home (couple weights, etc). When I'm stressed, I have a way to burn some of it off. It doesn't replace getting out of the house, my W says. She feels very couped up being in the house all the time with the kids. I hope you find a plan that you can fully enjoy regret free. Do you have a rec center with kids' programs?
