We had a few problems early on. Probably around May 2020 time. Maybe June.
But we resolved it by making sure when things were open we did plenty together. We also worked in separate areas of the house and didn't really interact all that much during the day.
He was made redundant in early March 2020, so there was added stress of that. We decided he would stay home while the kids were off to help home school so I could work.
We got back on track by realising that this wasn't forever, we just needed to get through it and where possible have time apart.
It was also important I got time to work, though there was no expectation of people being quiet or not using common areas. But also, he needed time without the kids. After schooling them all day.
He is back at work now, but wfh most days. And we really enjoy it. I am hybrid on a permanent basis. But mainly at home. The days we can have lunch together or a morning coffee, is lovely.
I have to stress though, in our situation. No one was at fault. It was just a difficult situation and we forgot to act like a team for a short while.
It really does, depend on exactly what caused the issues and how long it's been going on.
