Rent/Budget - Couples

An

How do you and your parter decide the amounts you both put in for rent? We should be moving soon and I'd like to assume that we're not gonna be making the exact same amount. With that being said, I'm trying to figure out how we should budget. Does the person with more money put more towards rent? Is it 50/50, no matter the difference in pay? Please comment any advice you may have. I truly appreciate it :)
