It sounds like you did get a break though when your parents took them to the zoo or museum. My daughter is 4 and both sets of grandparents have never taken her for a day out and both sets are retired!!
I remember the times parents came to visit to see the baby when newborn/toddler. Not only was I hosting, sorting out food and drinks for everyone, I was also wrangling a baby or child while they looked on from their settee.
I'm glad to hear you didn't need a break after working full time and looking after 3 children whilst also planning days out to keep them socialised (of course you didn't turf them out all day during school holidays and let them play on the street where they were susceptible to paedophiles and other rogue characters from a young age-that's definitely not a break of 8 hours is it).
I'm sorry you didn't feel the need to spend time with your husband too. I get it, why bother. As long as he can look after the children while you go out that's fine.
Obviously if a woman doesn't want to be a mother they shouldn't have children. Of course!!
What you haven't considered are the mothers who do want their children, love them dearly but also would like to spend time with friends or husband as being a mother isn't their whole identity. They are also a career woman, a book nerd, a pottery enthusiast, an artist, a wild swimmer, a wild camper or even just a gorgeous nail girly.
