<human>: I am an MD who just finished my fellowship in interventional cardiology and accepted a position in my city for $425,000 a year.  My GF who I met 2 years ago during my fellowship makes $47,000 a year as a HR employee at a small company.  

Since I've started taking home paychecks, she has been more lavish with spending.  She often insists that we go out to eat rather than cook at home.  She also mentions wanting a newer car and wanting to move to a  nicer part of the city.

Even with student loan repayment I can afford all of that, but it doesn't really sit well with me.  The main reason is that I feel like I've worked so hard to get to where I am now.  I spent over 10 years AFTER college not making a decent salary and being buried in student loans to get here.  I worked 80+ and 100+ hour weeks during residency.  I spent so much of my time pleasing assholes and running their petty errands.  On the other hand my GF has no further career ambitions.  She's happy with where she is now.  She spent all of her early and mid twenties traveling the world.  

I just wish she was a bit more ambitious and made a little bit more money, not because we need it but because it would make me feel better.  

My feeling may be completely wrong though.  Be honest with me reddit, is this my problem?  How can I work this out?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: I make 425k she makes 47k.  I feel like I've worked hard and she's reaping the benefits of my hard work without having any goals for herself.
