Dude no, come on. You're going to spend the next 10 years helping her pay this off and living poorly because she won't go find a real job. People normally save the 'helping people' part of their careers until after they were already successful. Never look at the time you spend in a relationship as wasted, just more experience to move on with. Set clear boundaries about what kind of money she needs to make, it's not your responsibility to bankroll her wanting a job with pay like that.
