Are you "crazy?" No. I could see how someone might reasonably decide that Michigan/Virginia/Penn are worth sticker given the median outcomes for graduates at that school. That doesn't mean it's necessarily a desirable or ideal choice, but it's a defensible one.

270k+ in debt, along with a pretty high interest rate, can make for an uncomfortable situation, especially if you discover that 3+ years of BigLaw is miserable (and a lot of people do.)

It may seem at the moment that the best thing for your relationship is to go to a school near your SO but given how often money can place a lot of strain on a relationship, the more sensible thing to do might be to keep your debt down now so that you can have a more enjoyable post-grad life with your SO.

Obligatory "what are your stats?"
