Long time lurker, first time poster.
My fiancee and I are both focused on growing our mustaches. We're about to graduate from dental school with an astronomical amount of debt, but we have solid plans for paying it down as quickly as possible. My fiancee, however, has some not very frugal parents that she will be supporting. On the surface, her parents seem like they have all the basics of a frugal lifestyle- Biking, DIY, infrequent dining out, living close to work, etc. The problem is, they don't live by the math. They splurge all too often on things like organic groceries, top of the line home gym equipment, and North Face brand everything. They both have steady jobs with a household income of over $100k, but they have still carried credit card balances over the years and they have recently been "forced" to sell their very nice home and move due to changes in collective bargaining laws in their state. They were living so close to the line that they couldn't sustain their lifestyle after losing a couple thousand a year in benefits. My fiancee wants to keep our finances separate, because she says that she alone will be helping her parents. I see this as inefficient and enabling, but I don't want to seem like an ass bringing it up with her. She is very touchy about them having to move out of her childhood home, commenting often that they got screwed by state politics. I want to help her and her parents, but I don't want this bleeding wound in her bank account that will not even solve the problems behind her parents' financial woes. What should I do?
