Once you get married, you share joint assets and your are joined together as one body. Either way, those loans will need to be paid off unless you go into the marriage planning to divorce (which is just planning to fail).
One of the biggest causes of marriage failure is money fights. Both parties need to be on the same general page how to handle finances. Otherwise your chances of getting a divorce are pretty high.
No the reason people divorce is not having a strong foundation and lack of commitment, I fight with my wife often about finances, specially over the past 2 years when I've been the sole provider while she finishes up school, there will be fights in a marriage, you gotta be prepared for that, doesn't mean having financial issues you gonna throw your vows out the window, remember "through thick and thin" from reading a lot of Nters replies on the topic of marriage in just gonna assume those against it are just selfish individuals....which is cool...nothing wrong with it, you want to put yourself first....because every time the whole marriage thing comes up, dudes bring up $$$$ and that's what marriage isn't about, if you love the woman, you are gonna take her with all her baggage and learn to work together to bring out the best in each other, this whole "get your **** straight and pay off your debt, then we talk marriage" steez ya preaching sound like the words that should be coming out of someone's mouth that is far from ready to take the plunge.
