I would say divorce because if you and your significant other are having hard times and are really stressed and endup getting a divorce then I would assume that all that stress has taken its toll on both of you or maybe just one causing you or again both to come to the decision to get divorced. because stress is a big deal in marriages.
Getting divorced can be very stressful on everybody included in the process. It can also be stressful on the divorcees. Divorce is a large change in life and long term. Moving to college isn't very stressful, although adapting to a new situation can be a bit hard. This is almost the same as moving to a new city. Getting a new job can be good and bad.
