Not really an IABU, just posting for traffic.
You're 6 years into a relationship, 2 DC. Your OH was fantastic for the first few years, but after a traumatic incident he needed therapy for a year and went on needing help with medication and still has bad days (unable to sleep, flashbacks, panic attacks etc)
Aside from that he's home full time as due to an undiagnosed issue with his joints he can no longer stand or walk for long periods of time. The pain is mostly in his hands, back and legs, every day.
The things he does to contribute are:
Feeding the dogs and joining us for walks
Majority of online shopping, meal prep etc
Cleaning toilet, sink (can't do the bath)
Hoovering (we have a very lightweight dyson)
Uses the steam mop in the kitchen and bathroom
Dusting/polishing/General tidying
Cooks if it's a quick easy meal
Dries and stacks dishes after I wash up
We take laundry days in turns
Nappy changes for the youngest DC in turns
Reads kids bedtime stories, dries and dresses them after a bath as he can't bathe them anymore
However you're doing pretty much everything else.
Does this sound okay? And if it does, why do I feel so resentful some days? He's kind, wonderful, caring, loving...and yet still I feel down most days as I trudge through the majority of the housework
