I'm not expecting any money from my parents or from hers.
I thought I already mentioned it, but we both had over 100k in student loan debt when we graduated. We paid them off aggressively at the same time before buying our first home. Looking back, it would have been wiser to make minimum payments and invest the rest instead but having no loans is definitely less stressful.
I handle all the finances which is why I have all of my wife's financial stats. I do the taxes, pay the bills, etc. She had no knowledge of 401k or Roth IRA before we met, so I helped her set those up. I do not control her finances at all, she is free to spend whatever she likes.
I see a lot of married couples say "I paid off my loans but he still has X amount" or vice versa. We never thought of our student loans as his or hers, we paid them off together from our joint account.
Also a lot of people are calling me a gold digger here. We dated for 2 years before deciding to pursue grad school. We both went to grad school at the same time as struggling students. I did not decide to marry my wife after she got her master's.
Yes, I was in a position to marry an ex girlfriend from an upper middle class family, who was accepted to med school at the time. We broke up before she started med school. I believe she is a doctor now, but I haven't been in contact with her in years.
I'm not sure what a predatory marriage is so I can't answer that question.
