Saw my parents and in-laws every 3 weeks for 25 years. My fil died just before our second anniversary, and my df 8 years after that.
They both lived 50 miles away, but about 10 miles apart. We used to go to my parents for lunch - arrive after 11 and leave about 5. Then we'd be at mil's until 2am - even when she lived at sil's for 7 years after fil died.
We reckoned that it was worth ruining 1 complete day.
Mil had anxiety neuroses, and so never got through the grieving process after fil died, so it was tough going to see her, as she didn't accept me for the first 10 years we were married. She was fine beforehand until she realised that her youngest ds was going to get married, leave home, stop paying her gas and elec bills and move out of Liverpool (even worse, go "over the water").
There was a period of about 4 years when after leaving after 2 in the morning we'd be driving home along the Dock road to go to Preston up the A59 in a clapped out car and get stopped by the police every time. When they saw us both they just used to wish us a safe journey home. Had it been just dh on his own, they'd have probably searched the car to make sure he hadn't been nicking stuff from the docks.
Eventually, I was much closer to my mil than I'd ever been to my own dm who tricked us into selling our home and going to live with her. That ended in tears, and we left after 6 months, and I only spoke to her once in the 20 years before she died.
I hope we see more of dd than that, but I doubt it. She's at lycée 130 miles away and has moved into a studio for her last year. She's then planning to do a course in Paris - 600km away - and live in Reims after that. At the same time we're planning on selling up and moving 120 further away.
We're likely to end up in a small village, and dd wants to be a tattoo artist, so I imagine we won't see that much of her.
