I want to ask my husband to find something to do and be out of the house on an evening when I'm inviting friends over for dinner
Why don't you want him there?
I don't want him to be rude to my friends.
It is rude to kick him out when you have people over. You can try to set up a special night for him to do something while you are busy.
Nah, what's important is that he does what I say. By being around he can distract my guests.
I hope you are kind when you suggest this to him. Do you think you could send him to a movie or a sporting event with a few buddies?
