You and I seem quite alike. I had been doing more chores and house cleaning. It was to appease my wife. I have found that the more I do, the less she does. She just takes advantage. I have since backed off.
The air of superiority goes hand in hand with Dobson's assessment that the spouse has been devaluing us. Now they have reached the point where they openly show their disrespect. Not only will my wife show this to me, but she now is starting to show it to others through her arguing any point I may make in a conversation with friends. I would also say that she is showing it through her late night partying with her friends and her not returning home until 3-6am the next day.
