I friend of mine, now mid 50s, parents split when he was young. Mum moved abroad with new man and he didn't see her again until that relationship broke down, when he was 23. That's not the bit I'm asking about though.
He and sister, three years younger, stayed with Dad, who seems to have raised good kids. They're all very close still.
However, when friend was 14, Dad's employer moved their base 200 miles away and Dad was working away M-F , leaving friend and 11yo sister to look after themselves during the week.
It sounds like they were fine, they both see it as dad doing what he needed to do, but shouldn't "someone" have been on that?
