I see you have a wife and Children, they are your priority.
Can you return to your current line of work if you do not gain employment as a pilot and if you do gain employment as a pilot can your total family income sustain your current life style?
How old are the children, young and moving them will be easy, secondary school and not such a good idea to up sticks.
I had a brief spell in Nigeria and a longer spell based in Germany, would not have expected my family to move and did not ask them to.
Working away can be tough on your domestic situation.
50k is a lot of money to gamble on a career change, flying for a living is a good job but not worth risking your family's life style and contentment for.
Tough choice, but only you know your personal and financial situation.
