Ken, I know what you mean... I am the one pushing for the move back (I'm American and my husband is English), but there's always a little voice in my head talking about the wonderful things here - beauty, I love the weather etc... But it seems that the fundamentals of life - finances, health care...are very difficult here.
My husband works 7 days a week as well and often works into the night. The other night he worked until 3am on a paper and then back at work the next morning! He has to cycle to work as we can only afford one car. It isn't right....
We too feel that our son would have a brighter future in the US and he can certainly choose when he gets older where he wants to live!
So, I hear you and I am sure we're not the only ones who are torn about the move. We are in the process of all of the paperwork, medical, etc and hoping to then have an interview soon.
