167.2 kilometers each way! after a year of doing this 2-4 times a week, I decided to rent a room in Frankfurt. I knew it was only a matter of time before I died on the autobahn, the commute was killing me and taking my car with it. My DH did the same thing when he got a job in another city, rented a room during the week and became "weekend dad". So far, this arrangement has worked well for us, but we do not have kids and the dog has two residences. My sisters husband drove from Rochester, MN to Minneapolis every day for his federal job. It almost cost her her marriage and she finally encouraged him to leave his gov't job and just find something else. It also helps that she has a 6.5 figure income. Just as he was about to quit,a job opened up in his town, which saved the day!! He did it for 4 years, and went thru 2 brand new trucks. I asked him why he didn't just rent a room and come home on weekends? it was because my sister was not really understanding of how this commute was really affecting him and just would not even process the idea of him becoming weekend dad!! What works for some will not work for others, I personally have no problem with geographical separations for work!! as my DH currently lives and works in Abu Dhabi, is it hard, yes, but I am grateful that he has a job! Do what is right for your family but do not underestimate the real expense of such a long daily commute.
