Life is always full of changes and IMHO needs to be embraced and met with positive feelings, hope and excitement for this new phase of life. We usually have to make decisions based on the facts we have today and reading what you wrote this seems like a good thing for you to do. I have a friend who commutes 90 minutes one way every day because he wants to raise his children in the country, but works in the city (smile). He listens to books and/or uses the commuting time to relax and really be at home when he is home.
From what you wrote, I think you believe this will be a positive. Go for it and keep us posted. We are behind you all the way.
