Is NOBODY wrong in the post ? POST : So basically, my girlfriend, G, and I were making lunch. Her older sister, S, (that my girlfriend doesn’t really get along with) got mad at something G said. The two sisters started having a yelling match until eventually G said “you know what, I’m don’t even want to eat lunch any more” and stormed off. 

Seeing as I’ve seen this type of thing before, I assumed she would still want to eat, so spent the next 10 minutes finishing off her lunch and making it just how she likes it. Next minute she comes back in, looks at her food, says “I said I didn’t want to eat” and threw all the food I made in the trash - and then stormed off again. 

I was pretty shocked and kind of hurt, so I finished making my lunch, and went to her room. When I came in I told her “that was a really horrible thing that you did, and I’m not talking until you apologize”. 

Fast forward to now, she told me that I’m the one who’s the asshole because we had agreed that we would talk about the problems we have with each other. And by telling her she needed to apologize I was asserting my power over her and the relationship.

AITA?
