The tactics are myriad:
My ex used to make me decide and make all the arrangements for whatever we had to do at the weekend (and we had to do something because "I am not sitting around doing nothing on my weekend "). Therefore if we had a great time, he had it without effort, but if we had a terrible time, then he could blame me because I was the one who'd come up with the idea and planned it. Ditto for every holiday.
Always answered a question with another question:
"Would you like to go for a walk with me this evening?"
"Why would I want to do that?"
"Where are [younger son's] swimming trunks?"
"Why are you asking me?"
"Because we're leaving tomorrow and he hasn't finished packing yet. Have you seen them?"
"Why would I have seen them?"
(this could go on for a while, when a simple "no, don't know " would have sufficed)
"Why is the car so dirty, have you been driving around in mud today?"
"Why would I be driving around in mud?"
"Do you want me to get you something from the supermarket when I go?"
"Why would I need you to get me anything?"
"If you're so unhappy in the job, would it be helpful to retrain to do something you have always wanted to do?"
"Why would you think that would be helpful?"
It seems to be a typical response you get from insecure people, and I've experienced this in both men and women.
And treated waiters in restaurants like they were service creatures beneath contempt. It was embarrassing how he spoke to them.
Don't ask me why I stayed with him. After a few years, I guess I thought it was normal. I didn't even have the vocabulary to describe it to anyone else, so I never told anyone. I used to try to explain it to him ("Why do you always speak like that to me... etc.), but I would get accused of "policing his speech." Sometimes I want to slap my younger self around the head with a wet fish!
You've got to laugh otherwise you'd cry.
