I like 50/50 in a relationship

im only accepting 90/10. the only things ill be contributing to are groceries and some household chores :)
Is that so? To me it’s 50/50.
For example, if you take her out for a movie and dinner, and she buys a outfit and lippie for the date, hence it’s equivalence to 50/50.
I don't care if she comes with me on a date lookin like a walking Gucci store or wearin this

She must pay her half of the date
