I have the same problem.
My new work place is far away from my home (4 hours round trip). My hu*****and said it is impossible for me to drive to work every day, I have to rent a apartment nearby and only come back home over the weekends. I have two children too (8 and 3 yrs) and my hu*****and will have to change his work schedule from full time to part time!
It is hard decision for me! Life is not easy, what's the most important in our life?! Money? Happiness? Family?...
Good luck!
