DH just retired in June. He was burned out, and we'd reached FI, so he was free to quit.
My job is a separate decision. We are FI, I could quit if I wanted to, but...it just isn't time, yet. I was SAHM for nearly 20 years, and started working part-time after the youngest started school. That extra income helped get us to FI sooner, because we could save more. But DH's income was always the main one, and he had all the bennies, especially access to retirement accounts. So the bulk of our retirement $$ are in his name (outside of some Roth IRA in each of our names). My SS earnings are pitiful, too, with so many zero years and only part-time after that (college earnings never got reported, because i worked for the college). So I'm still having fun at my job, I want to up my SS record, I finally got a SIMPLE IRA a few years ago that I'm maxing to get a bit of a balance in my name in retirement accounts (state taxation of retirement accounts means that some in each is much better than all in one), and we still have a teen in the house. As long as we have a dependent, we need a bit of earned income to be eligible for refundable tax credits like EITC. And that teen at home limits things we might choose to do if we were both free. All around, it suits me to keep working a fun part-time job for a few more years, even if we don't "need" my income (planning to put most of it in retirement accounts anyway).
The Covid shutdown last year was a great trial run for having DH home all day, after working for decades. He had lots of projects to catch up on around the house/yard, and things to explore now that he had the time. We didn't get on each other's nerves being together 24/7 then, it was really nice to get to have more meals together, consult each other on plans for the house, etc. Now that DS5 is back to school full time and my job has returned mostly to normal in person, DH has pivoted to being the more available spouse to handle appointments and other stuff (we've really realized we like the slower pace and less busyness we had during the shutdown).
