We are quite settled, 3 kids, nice house etc.
Then the opportunity arises for a sea change. There's pros and cons. My biggest issue is leaving what I know and dragging the kids away from what they know. They are dd 8, ds 6 and dd 4. The eldest 2 are happy at school. Youngest starts next year.
Also it means leaving my sister and her 4 kids and we're all very close.
The upside is new beginnings, seeing and living in a different area, financially may be better.
