Ok, first, let's make sure we keep this friendly. Money isn't one of the top reasons couples divorce for nothing--it's a highly emotionally charged issue.
I certainly can see both sides of the issue of loans vs. having someone help you pay for school. I took out loans and paid my own way through my masters program. I agree with clawbeatskin that it definitely built character for me. It was the first time I'd done anything that huge on my own and I still feel a strong sense of pride about it. My folks also offered to help, not in terms of straight tuition, but they offered to help me with other bills and such. I didn't let them for two reasons. First, I wanted to do it on my own. (But their help wasn't going to make the difference in how much loan money I needed, it just would have helped make me more comfortable. If it had meant not having some of the debt I currently do, that might have changed things.) Second, my parents are coming up on retirement age and I don't want to be taking away money that they could be putting towards their own futures. They paid for my undergrad (in addition to giving me every advantage they could while I was growing up) so they've already done so much for me.
On the other hand, though, there's nothing beautiful in being a martyr. If there is someone around who can help you out financially with school, who is willing and able to do so, and it won't significantly negatively impact them, you're not proving anything by taking out loans. My SO will be helping me pay for school. We're planning on getting engaged soon and married in the next 1-1.5 years but won't be married for the first year of school. Nevertheless, my debt will become his debt when we marry, so it just makes sense to incur the lowest amount of debt possible. A slightly different situation is that my brother has also (in the past) offered to help pay. He's not really in a financial position to do so at the moment (his career, while extremely successful, is just taking off), so it's a non-issue right now. But if he was in the position to help me pay, and if I was sure that it wouldn't damage our relationship somehow, I would probably let him help me with school.
These are big, personal decisions, so it's easy to see why we all might have different approaches.
