@Fraaances suggestion works perfectly.
Years ago my dear friends husband was overheard agreeing to a visit of his parents without checking with her.
She decided to box clever and asked could we do something for the day.
I said I can do better, lets head off for a night to my holiday home.
He never said a word, but he had a habit of not telling her things and thinking he had, AND he had a habit of not listening to her when she was telling him stuff.
So a full week later he mentions it finally that they were visiting, staying the night and she was all, "fine, no problem, whatever you like".
He looked at her surprised and eventually came back to her asking was it really ok?
She said of course its fine, I'm away with Alice so whatever you plan to do is fine with me.
He was horrified. He couldn't cancel as it was a week later. She just said I told you I was going away weeks ago for a night.
She asked me to collect her as early as possible and I was there for 9am and off we trotted.
He had two children to look after, and she had neither tidied, shopped, prepared a bed, absolutely nothing done after a weeks work.
We had a great night on the vino and he ended up getting a takeaway.
His mother was outraged at how little was done.
He was like an antichrist when she returned and she totally ignored him except to say we had a great time and would do it again soon.
He was a great man for a days golfing.
It was such a cheap night away we made it a regular thing for years.
Every time he mentioned he was off for a night, she said no problem Alice and I are due a night away.
It took the shine off the nights away, and he reduced them substantially, and he certainly never invited his parents again without consulting her.
Talking is often useless with some men, a dose of action works far better.
