I thought I'd be bored shitless too.
I'm honestly not.
I do miss my colleagues, but chat to them regularly via WhatsApp etc (which isn't the same) and have gone out to dinner with a couple of them a couple of times.
I think if people assumed less until they'd actually tried it, there wouldn't be such strong opinions of how trivial and tragically dependant my life must be. Opinions that I was certainly guilty of at one time too. But it's hard to explain unless you've experienced this at your own choice, why it's actually far from unfulfilling.
Another thing I've noticed is that we're a lot more appreciative of each other now. I appreciate how hard DH works in order to finance all of us. I appreciate the time we have together and find myself making more effort to make those times special. He appreciates the efforts I go to, to make really good food for us all. How the house is always full of flowers and smells lovely. Tidy, easy to find things, all the admin done so he has to think of nothing but relaxing when he gets home. He and DS both love coming home and seeing what's in the cake dome for the day. Former me would laugh at how pathetic that sounds. Current me looks at former me and thinks, if only she got her head out of her suit wearing arse and remotely considered the happiness you feel from seeing your family happy because of something so small each day.
DH likes that I have time to keep my nails/hair/beauty stuff done. I like that I have the time to keep on top of things he finds attractive. I don't do it for him, by any means, but I'm not too stubborn and "girl power" to admit that it's a positive thing for your partner to look at you and think "she looks really nice today." When I was working, I still looked nice, but often missed appointments and couldn't always find the time to keep on top of things the way I do now.
He works. I don't. It doesn't mean what I do has less value. It has less monetary value, of course. But then his career brings zero to our family life other than monetary value. We respect each others contribution hugely.
But, of course, I would have refused to believe any of this whilst I was still working. Maybe an element of me was too aware of the lowly opinions of housewives amongst general society and my colleagues, so I didn't entertain it ever as an option. Not when educated successful women such as myself found it all so pathetic. It must be unfulfilling and pathetic, right?
All I can say, from purely my own experience, is that the working crowd who imagine how mind numbingly dull my financially reliant existence is, are talking with false authority. Pretty blinkered to have zero experience of something, yet dictate how that experience must be.
And to balance, housewives aren't all happy. Those who have no choice but to stay home, thereby feeling they have been denied opportunities, those who despise cooking and household admin, those who have to penny pinch and have very little life outside the home because of it... They're not going to enjoy their day. Anyone in a role/job they do only because they have to, is not going to have much of a positive spin on that role.
