Try this idea on for size. The 2 kids that will most likely stay in town with dad are not counted in this due to they would not have to make drastic changes.
For the next 2 years, until the older child graduates from high school stay where you are. It is entirely crazy to drive an hour one way to take a child to school. They are in high school and do not want to change from their support group/friends at all. Unless they are extremely unhappy there they should be allowed to finish school. Then you get to come first.
Tell hubby he has until May 2015 (whenever graduation is for 16 year old) to get used to the idea that you will be moving closer to a nearby town. Of course moving part way so he can keep his job too is oddly not an option.
I looked up Decorah on the map and it looks like it is out in the middle of nowhere, I would hate it too. I am a city girl all the way, living in the suburbs is out there for me. I live in a semi rural area now and go to OKC quite often but it is still too "country" for me. I do it because hubby lived here when we got together. He has family land. It makes me stress a tiny bit to know I am going to grow old in the town and probably die and no one find me for days. Until someone can't get me on the phone and come to find out if I'm okay...
I hate out in the country. My dad died in the Arbuckle Wilderness area. They had gone there for the day and he had a heart attack. They tried to drive part way to meet the ambulance but he was in too bad shape to be saved. So I have very real issues about living out in "the wilderness"... I hate it too but I have to rationalize that it's really not that different from a few miles away.
We have a mobile home that is in bad shape, I hate storms and will leave my house for a sturdy structure when the wind is over 60 MPH. I will go to the local hospital's basement and sit it out each and every time.
I completely understand your wanting/needing to move. It makes all the sense in the world to me.
I suggest you sit down with hubby and let him know you want to talk about your future living situation. Let him know you want to hear his opinions and wants but you want him to prepare to listen to you too. This will help him to have, possibly, a more open mind.
By giving him a date in the future it will give him time to make the mental adjustment to living somewhere else. That fall start looking into housing, elementary school districts for the kids just now starting out, start making it a reality that it's coming up. Take a couple of long weekends and go to the other town and stay in a hotel to look at areas you might want to live, etc....
Giving him a date will help he see you are serious about this. BUT if he has valid reasons you are going to have to listen to him too. He should not have to give up everything for you too. A compromise is always a great way to work out the issues but not to the point one person is giving the other one everything.
