This is entirely from the perspective of a 13 year old whose dad ended up out of the home 4 nights a week.
There is no personal satisfaction on this planet worth the potential fall out.
The parent at home can become resentful of carrying the major load of the kids. The returning parent can find that upon arriving home they get hit with a wall of complaints by the home parent, and the kids about the home parent, who did what, which transgressions that should be left be get dragged up in time for the weekend/holiday.
Marriages can fray. Perhap temptation, once perfectly resisted by avoiding situations where temptation might occur, can creep in. And not everybody is fab at resisting temptation when they feel resentful, or like a weekend whipping boy/girl.
Not all marriages survive an additional layer of distance and “absence does not always make the heart grow stronger”.
The fall out of a badly frayed marriage, or one that does survive intact is hard enough on kids. Those that had just managed 2 years of parents tussling due to one being out of the home rather a lot, to satisfy their personal priorities might find it even harder.
Child/parent bonds can weaken over time with the not always home parent, especially if it was from parental preference rather than absolute necessity. It can feel like all the stress and ill-feeling was chosen freely, despite the downsides for the young ones with no vote in the matter.
Been there, done that, got the “fall-out” T-shirt.
I’m glad it happened to me, because it gave me insight that helps me avoid certain potential unintended consequences being my son’s life rain. Without those scars to remind me, I can see how a planned path might not illustrate clearly the thorny terrain that may have to be navigated. By all involved.
I love my job. I’m exceptionally good at it. But I can live with being a big fish in a puddle better than I can live with the potential price for my boy if I strike out to swim in the sea with the other big fish.
