I empathise with you OP. But you need to reframe it.
In the last recession, DH got a contract on a job which meant he was away, literally the other side of the globe, for 2 weeks. He left Sunday mornings and got back at lunchtime on Saturday having travelled through the night both directions.
When he was here, he also had a FT job to do.
I was working a very stressful FT role, and expected to do a lot of unpaid overtime.
Dd was in primary school, and had recently been DX'd with SNs (high functioning but still needed management and support ).
We got au pairs to help with school run etc, but I was still paying for ft cover in after school club as AP hours meant she couldn't do both and morning was more important to me. It also meant there was always someone else there which was fine with some of them, but I literally was never alone to just slob - I was always having to chat in the evenings.
We were under pressure to go visit DPs and DPILs on the 1 weekend a month DH was at home all weekend, they lived almost 3 hours away.
We just got on with it as there was no choice for 4 years. DH found it hard. I found it hard. DD found it hard.
He did not have a fun time while away, he worked 12 hour days and lived on microwave dinners. In a place with high crime (literally car jackings at gunpojnt and more than once their rooms being broken into while they were asleep in bed).
