You should be paying a higher portion because you make a lot more. Since you make 77 percent of the income you should be paying 77 percent of the rent and her the remaining 23 percent. Its the only fair way. 50/50 is fine if you make close enough amounts . This is not the case here though. 150k vs 500k? That’s a big difference. Going 50/50 there means you get to keep way more of your money than she does hers. That’s not fair. Going 50/50 when there’s a bigger income difference really isn’t fair …
