To move or not to move?

The moment of truth is drawing nearer... Hubby has been to an interview in the UK, and as it looks now he’ll probably be offered a really good deal… Now, do we take the opportunity to move back, as I’ve been bitching about for nearly 2 years now? Even though I don’t like the place we’re in now, my worries considering a transfer are so many…
1) Have we gone too far in the metamorphosis of adaption to simply go back to our old life?
2) Will F be far behind in school and suffer major stress in catching up?
3) Will Fs friends still hang out with him or have they moved on?
4) Will it be too tough a change for E who is just now coming out of his shell socially and bonding to friends?
5) Will cheeky monkey P with ants in his pants be ok in the disciplined UK school or will he get into trouble, branding himself as a menace?
6) Will hubby have any energy left to enjoy family life or will work suck him dry and then some?

The grass is rarely greener on the other side, they say… Is this true? I know life in the UK is more interesting for ME. I’ll have all the opportunities I could ever wish for to develop and create a life for myself once the boys get older, and I’ll have lots of fun activities and a social life during the years I’ll be staying at home. The boys will also have greater opportunities over there, to be all that they can be when they grow up… Still, will we regret the move if we do it? They’re children NOW… They need their dad in their lives NOW… They need their friends and social networks NOW. We’ll never have these years back if we ruin them by going in over our heads… Our boys won’t get second chances of a happy childhood… If this chance had been given to us a year ago I would have jumped at it, no question about it. My fear is we might have been here for too long now, the biggest catch being I have gotten used to having my husband back, and the kids have gotten used to having their dad around. If I’ve learned something from life it is that all the places you live in for more than a year change who you are, without your taking notice of it, until you move that is… I suppose all that can be handled though. We know pretty well what kind of life we’ll be moving to. There will be an acclimatization process, but probably an easier one than we’ve experienced before because for the first time ever we would be “going back” to something we already know. To be plain and simple, what worries me the most is Hubbys work load. Will he ever be able to relax and enjoy spending time with the rest of us or will we just be in his way as he’s trying to keep his nose above the water with the work stress?
