I found out my fiance's parents want him to break up with me because of my student debt...feel even worse :/

long story short I have a lot of student debt and still have 2 more years to go until I start making any real money in my field. It IS a lot of debt, and I was very up front with him from the beginning. I told him I don't expect anyone to help me, but I was realistic and said if you want kids sooner rather than later I will need financial help with this. My fiance makes about 50k a year and I make very little right now becuase Im just starting out but once I get experience I can command at least 65-70k minimum. Ive struggled a LOT with feeling like a failure becuase I took out so much loans to start with and I changed my career becuase the first one wasn't my passion and wouldn't have made a lot of money anyway. Its been incredibly hard. I can't even afford to fix my cracked teeth or get a nightgaurd that I need to prevent more teeth from cracking. I work all the time and study every night and Im so fucking exhausted. The stress HAS been getting to my fiance though. He grew up with parents who were very well off and I don't think he knows how to handle this. He has decided to get therapy becuase he has developed anxiety and I fully support it. I feel so bad becuase I know his life would be so much easier without me. But he says Im worth it. He says he knows this will be better in two years once I make more money and he doesn't want to miss out on me because he wasn't patient. Either way, I wont let him marry me until my position changes financially. I do NOT want to trap him. I found out his mom (and possibly his dad) thinks he should just break up wtih me. They think that while Im a good person, my past mistakes are just going to bring him down. This really hurts. I dont know how to forgive them, and I can't even look them in the eye anymore. The worst part?? His dad supported his mom entirely through med school. The only fucking reason they have money is because he took financial care of her while she was incurring debt. I realize the situation is a little different here, but it feels so fucking hypocritical. I just feel so bad and so ashamed and like a failure. All Im doing is trying my hardest and to hear that I dont have their support kills me. Recenlty she messaged me on fb saying my status changed and she wondered if anything important changed. Idk what she was talking about but I feel like she was hoping we broke up!! Idk what to do :(
