My parents are also in no position to help out on my loans (most expensive school in canada, just my luck) but even though I'm still studying and struggling with a part-time job, I help them out when they need it and they try to do the same and it's that simple.

But to clarify the LW's position: her parents helped as much as they could when she was studying. She graduated, got a stable job, the parents are still in the same position and now she's expecting them to help out MORE?

If I was in her place, there would be no doubt in my mind that I would be helping THEM by assuming the costs of travel for visits, ensuring their own comfort, and then not asking any more than the love and support they've always offered. Because, well, they did kinda give me life and all.
