I went through something like this when I was married to my daughters father, he was always giving me the “ your too strict blah blah blah
In your case ... can you just let things go ??? let it all go for as many days as it will take your husband to get a flipping clue? I know beyond hard but let her miss her bath, fix simple meal I’m thinking grilled cheese , eat and leave the table , let her sit there , let your husband deal with it.
I hope you find some kind of mutual agreement, you are is a shyt position I feel really bad for you
Do something nice for yourself ! Just you !
