<human>: Can you condense the text into three sentences or less?

The background:
I just finished medical school and I'm starting residency in July. I have $240,000 in student loans to pay off, and I'll be making about $50,000 per year. She is a family doctor with no debt and is making about $150,000 per year. We're married but she got me to sign a pre-nup, so my loan is all mine to pay off if we ever separate. We've been together for 6 years.

The dilemma:
My loans have a high interest rate, so I want to pay them down as quickly as possible. I suggested that she could cover our living expenses (rent, groceries etc) with her salary so I could use my entire income to pay off my loans. Because it's not OUR loan, and she doesn't want to contribute to paying it off, then that is my #1 priority as I'm only getting deeper in debt. 

In the end, having it paid off soon helps both of us, as the sooner I pay off my debt the sooner I will be able to start contributing towards mutual investments like buying a house. Does that seem fair?
<bot>: Should my wife support us with her large income while I use my small income to pay down my student loans, or should we split all the costs 50/50?
