Hi Suzanne and all,
I'm fairly well aware of the constraints in living in the UK. I've done salary shopping, job availability searches, and so on. I live in a house that would cost four times as much if it were simply shipped to California

Because I was previously engaged to an Englishman, I did a lot of research on the difference between the two countries.
When I was in England in August of this year, it was HOT. That's not the norm, but there was no escaping it either due to the lack of air conditioning. But I grew up in a 900 sq ft house without air conditioning, with parents who were and are of very limited means. On my stay in the UK, I stayed in council housing near London, which was about what I expected. I also stayed at friends' houses across England, and saw big disparities between regions.
I've had money, but I found out that you can't buy your way to happiness. I was in an abusive marriage where I had all the money I wanted .... so long as I didn't put a toe out of line. I'll take happiness over money any day, so long as I have the bare necessities, and that's pretty minimal for me.
The children are the hardest part. I made my commitment to stay here with them until they are both 18, barring some really unforeseen circumstances. I was offered money to leave and give up sole custody to my ex. Instead I stayed and fought.
I do appreciate your honesty, because I know that there are Americans who think that the UK is Harry Potter-land or Beatrix Potter-land or .... my mother would never get past the 4% regular church attendance rate or what I perceive to be the higher acceptance on the street of cussin' and casual shags. That isn't to say that there aren't places she would love, but as you say, only on holiday.
