<human>: Hi /r/Relationships, throwaway here for privacy.  I'm a grad student and my boyfriend works in finance.  We have dated since college and have been living together for 3 years.  Overall, relationship is stellar - marriage and babies are happening in the not-too-distant future, we are crazy in love with each other, and we have wonderful and open communication.

However, recently we have been having some conflicts over money (I know, I know, most common source of relationship drama ever...).  I make about $25k and he makes about $140k.  Together, we live well within our means, but individually I feel like I am floundering at the end of every month while he puts away a few thousand in his savings accounts.  

We have agreed to split the rent evenly ($2500; we're in a mediocre apartment in a pricey city) and we have a lot of conversations that go, "Hey could you cover this?  I got the groceries last week," etc.  All said and done, we probably split expenses between 50-50 and 60-40 - in which case he takes the larger share.  Both of us value "fairness" but I think to him fairness=equality whereas to me fairness=equity.

I feel guilty for wanting him to cover a bigger portion of the shared costs, but at the same time I'm making SIGNIFICANTLY less than him.  Does anyone out there have suggestions for how we can talk about this?  We have kept lines of communication open but I think we'd both benefit from having a new perspective.  I just want us to be able to move forward.  If it's relevant, I know he's saving up for a ring, and we have no debt.

Condense the text into a few key points
<bot>: I (little money) feel guilty but justified in wanting my boyfriend (lots of money) to cover more of our shared expenses.  Anything we should be thinking about or talking about together to help address this?
