DAD,
Didn't say that life in the UK is more interesting than in the US... just that it's interesting!
Not a day has passed since I moved to London five years ago that I haven't thought about going back to the US. It's a bit of a mania. My motives are not quality of life. I just feel like I left the place that made me tick for a kind of, I don't know, experience. So I can understand why you would want to go home to the UK, because being an exile is not for everyone. Perhaps you needed a whole set of rationalizations to go with that very understandable urge because you had acquired a family. People really are trying to have it all now, to nurse and understand every feeling. Once being an immigrant meant that you had permanently left home. Now it is not necessarily so simple, or so complicated. If your wife hasn't thrown herself off a bus she is coping reasonably well given the circumstances. (And the weather has been quite lovely). Now try to do what you had set out to do, and if it doesn't work you go home, wherever that might be.
