I have noticed this a lot with my DP. One rule for him, one for anyone else.
We eat breakfast together. He stands preparing his breakfast in the way of the kettle, the fridge or anywhere else I would like to get to to prepare mine. So I wait for him to finish, then prepare mine.
If, however, I end up in the same spot first preparing mine, he is constantly saying "excuse me" whilst gently pushing me out of the way. He can't wait. I have to move out of his way.
I pointed this out this morning and he said "but I can't get to anything because you're in the way". I pointed out he stands in exactly the same place every single morning and that I simply wait for him to finish.
He then sulks throughout breakfast because I have dared to ask him to have some manners and treat me as I treat him.
Not a big deal is it?
Same with the TV, he channel hops constantly, puts what he wants on and I fit in, I don't care that much. However, if I pick up the remote and put something on I want to watch without asking him, I am accused of being selfish.
He corrected me in front of a friend at the weekend that "my" car is not "my" car, but "our" car (he paid half but the paperwork is in my name). His work truck, however, which is owned by his company is always referred to as "his" truck, never the "work truck" or "company name truck". He also has a car of his own too which I would never refer to as "our" car.
