Mine got divorced when I was 9 or 10 (just realized I can't remember the exact year...), and I stayed with my mother. My father didn't move far away though (about 40 minutes away with car and ferry), and the divorce wasn't a painful one, but I still ended up having very little contact with him. Perhaps a weekend every other month and a couple of holidays.
He was quite depressed for a while after having to start over after 15 years of marriage, so it wasn't all that fun visiting him some of the times. It's only the last few years that he's begun to seem genuinely happy again. He even has a new girlfriend. We've gotten a bit closer too, and speak regularly on the phone.
