I'm with you op. I sometimes feel like it's a kind of cultural gaslighting going on. The selfless loving mother image is very handy indeed for men (and children seem to like it too). If you complain about hardship, feeling overwhelmed and exhausted, you aren't following the self sacrificing script and might be guilted for it, or seen as a monster.
I've been through absolute hell for fifteen years with my two boys as a single mother, but people might feel uncomfortable if I say that and I might be seen as a monster not capable of love, so like many women, silence is often wiser. Except on here.
I'm out of the worst now (and it's still fairly bad) but it often felt like being tortured in an isolated prison camp. You couldn't pay me to go back to it!
The absolute loss of personal freedom, severe existential boredom, loss of a sense of self, housework, endless meals and snacks, school runs, fighting children, child centered activities. I could go on.
I too wonder why we don't talk about the years of domestic overwhelm more because I'm convinced those years are what gave me cPTSD and I don't think this is uncommon.
What kind of species are we as humans? We evolved to alloparent (in groups). Now we are often isolated in our own homes and I think this is where the strain comes from. It's a tricky subject because any complaints can be seen as a lack in you
I do realise not every woman has it this hard and many feel it's the best thing ever. That's great for them, but it's not so pleasant for many.
