I've said it before Steve, but it's important to say it again.

Never underestimate the scale of such decisions.

My circumstances were a little different. I had no family and no close friends in UK.
When my dad passed away I was aged 61 with almost zero chance of employment.

My wife and me had talked about it so many times.
She was getting more and more stressed at work even though she enjoyed it mostly.

We made the decision and followed a carefully designed plan.

One of my promises to myself and my wife was that I'd give it 3 years come hell or high water. Means however much I thought about returning I'd not make any decision to return until I'd given my best shot for 3 full years at least.
