@Blurp How did your PIP hearing go? Have been praying for a good outcome for you x
You're right - people largely don't consider male/male domestic dynamics. It would be a fascinating social study: perhaps researchers will come up with a report in the next decade... I know a chap in your situation. He has his own business and a few hours to relax after he finishes work, when his husband comes home and he starts his 'second job': being his husband's PA, making sure that the house is immaculate, all chores are done, and the food delicious. He becomes exhausted and frustrated sometimes, because he too is the lower earner, but without his contribution his husband's life would be in sad disarray. It doesn't stop him from feeling like a put-upon "wife" sometimes, though, and he snaps/becomes depressed/needs space.
I wonder - and *please* tell me if this is going too far; I don't want to offend you by making assumptions, ever - whether part of your current malaise is that your personal, emotional and intellectual needs aren't being met? My own mother was in your situation for years and finally broke out, got herself to Oxbridge and forged a career: she found her brain and talents atrophying and once I, a precocious child, could largely fend for myself (difficult when dealing with a covert narcissist and alcoholic father, but hey), she grabbed her precious freedom with both hands. What would help to change your dynamic and help to make the relationship feel more equal? What could your husband do to contribute to the hard hands-on work that is raising children and dealing with domestic issues 24/7? It sounds as though you need time and space for yourself, to nurture and cherish yourself, to use your evident and undoubted intellectual gifts to their fullest.
Again - if there are too many assumptions in this, I am profoundly sorry.
