We can't make them treat us any different. They will do what they want to do. If I have leverage, I may take something away for a certain treatment if they don't want to adjust it.
I can also not be around them.
I guess I would like to see how you would handle a situation of "my wife treats me like dirt. Her attitude is extremely negative, she projects bad emotions into me, always seconds guesses me, has no problem embarassing, switches into an obscene tone of voice when talking to me".
How can I get someone to change that without any leverage?
