<human>: Condense the text into a few key points

We've been married a year and had a joint bank account for over 3 years. Recently, my wife has brought up that she has always felt guilty for spending money. I make nearly triple what she makes, so I guess that makes sense. But I feel I've always told her she could buy what she wants. We've always had one rule, any purchase over a certain amount and we check with each other.

Recently, she has went through what I call a self empowerment movement. She has expressed feelings of having no control, no power, and no say in the relationship. Especially when it comes to money.

Currently, we pay all the bills out of our joint account. She has expressed a want for separate bank accounts. At first, I hated the idea, but I am trying to wrap my head around it. I was thinking if we had separate accounts, things would be 50/50 and she would just sink cause she couldn't afford that. Then she mentioned doing things based off percentage. I pay 72% of all the bills since I bring in 72% of the income and she pays the other 28%. 

It's an interesting concept I had never heard of. She says some other friends do it. For bills, it would be easy enough to split. And we would just each buy our own gas. But what about when we go out to eat? Or when we go grocery shopping? Or what about planning vacations? Do we just keep writing checks back and forth?

I guess I'm just curious as to what everyone else does or if they could offer us some advice? I just want us to be a partnership, but I also want things to be fair. Any thoughts?
