I agree with you OP.
And I have a career and a DH who earns enough for us to be able to afford a p/t housekeeper and several fabulous holidays a year.... to address the assumptions others have made so far.
I really don't understand what's so wonderful about being constantly demanded and put upon. Everything becomes an exhausting effort if you have kids with you (that "little bit worse" thing was spot on OP).
Could someone please explain the wonderful heart-warming moments and what they're supposed to do to me? Or the 'rewarding' thing? What is that? I'm approaching year 10 of being a mum and it's just fucking endless hard work. I'm dreading them getting old enough to go to bed at the same time as me, I'll literally never escape them. Without doubt all my favourite moments of the last 10 years have been times when DH and I have been away from the kids.
....And interestingly my mum was one of those who repeatedly said, through gritted teeth "don't have kids" and I found her advice hurtful and ignored it.... but you know what? She was right. I thought if I kept my career, unlike her, married a man with a well-paid job, got a cleaner and paid help then I'd make it all ok. But nope.
I've contemplated divorce so I'll get 50% of the weekends and holidays to myself - just weighing that up with the fact most weeks will be only me.
I have weekly psych counselling so that this feeling doesn't 'push me over the edge' but there's nothing that can be done. It's just shit and I'm stuck with it. I can't pretend myself into being happy with it.
