Is AUTHOR wrong in the post ? POST : Recently, my partner received two large promotions and makes about 3x as much as I do. I am a student, about to finish my degree and work on top of that. 

He pays a little extra in rent (only a couple hundred dollars) and pays for our dinners sometimes, but other than that we split everything down the middle. Groceries, stuff for our dog, house things, it's always even. He will always give me money if I ask, but that's just not in my nature.

He works for a large corporation where he has awesome insurance, and unfortunately they do not allow domestic partners to be on their health insurance plans. I, on the other hand, have very shitty insurance and have to mostly pay out of pocket for medical and dental bills (I had to take out a private loan just to pay for dental work, ain't America grand?). I also have an older car that I keep having to pump money into to keep it alive. 

I also want to mention I do 90% of the housework, I always feel that because he pays a little more in rent and has a high stress job that I want to contribute more around the house. Today we got into a big fight over it because he made food late last night and didn't clean ANYTHING- there was food left out, the stove had caked on sauce and the sink was full of dirty dishes. I, of course, cleaned up after him this morning. 

My question is, would I be the asshole if I were to ask him to pay more of the rent or contribute more financially since he makes so much more than me?
