I've read every page of this thread with fascination since I am a housewife who doesn't do paid work and doesn't have kids. There aren't many of us and, in my experience, people are generally befuddled and slightly hostile to the idea. I squirm a bit when people ask me what I do because I've gotten a lot of "Must be nice..." and "What do you DO???" and "I could NEVER!" reactions.
I have a college degree and worked from when I was 14 to when I quit in 2009 to take care of my ill mother. After she passed at the end of 2011, my previous employer offered me a position to return, but I realized I didn't want to. My work was something I was good at but not passionate about, and we found that my not having a job really worked out for us. DH is an exec in IT with long hours and frequent travel. We don't really miss the money I made, but we sure do appreciate the time that has freed up. With me in charge of the house and life admin, he is free to focus entirely on his career, which he loves and excels at. As it turns out, I love and excel at being a 50's-style housewife. It's a great arrangement for us. It also allows me to do volunteer work I am passionate about. Each month I read and distribute books to 300 Head Start kids and work about 50-60 hours at an education charity.
While no one can plan for everything, I've controlled for as much risk as possible. We have savings. We have insurance. If he were unemployed we can afford "affordable" care, as long as the congress-critters don't muck it up (if they do, I may think about taking some kind of job so we have a backup for insurance access). I have enough money entirely in my own name to support myself for several months if we were to divorce. I have credit in my own name and a network that would be able to help me get employed and on my feet again. It might not be glamorous or the same lifestyle DH can provide, but I won't starve.
The topic here is women without children that stay home. I respectfully am curious about it.
I completely understand your curiosity. This is what my fairly typical day will look like tomorrow:
8:00ish - Get up, get ready, do cats' morning medicine & food
8:30ish - Make breakfast, eat with DH
9:00ish - Morning chores - unload dishwasher, prep anything needed for lunch, take a look at food/house supplies and note what's running low, scoop litter, quick vacuum, gather trash & recycling, start laundry, tidy up
10:00ish - Financial planning and life admin - every day I balance the checkbook, review our credit card activity, monitor & research investments, etc. After that there's always someone I need to call or something I need to follow up on. Tomorrow I need to call about a doctor bill and start the paperwork to rollover the 401k from DH's old job.
11:00ish - Sprouts run. Our local Sprouts does "Double Ad Wednesday" where they overlap their weekly sales by a day. Their prices on produce, meat, and bulk bin stuff are good, so I try to hit it most weeks. Because I have the time and mental energy to do it, I try to shop as frugally as possible and take advantage of deals.
11:45ish - Put away groceries and begin prepping lunch
12:00ish - Lunch. Relax and chat with DH
12:30ish - Clean up from lunch, prep for dinner, switch laundry, small chores
1:00ish - Downtime. I might read, watch a recorded TV show, work on a hobby or project. Or goof around on the DIS *cough*
2:15ish - Leave for volunteer shift. I volunteer 3 days/week at a free store for teachers in underprivileged schools. It's amazing to see how hard the teachers work for their kids and I have lots of friends there that I enjoy working with.
6:30ish - Home. Normally I would make dinner for us and spend the night relaxing with DH. This Wednesday is special because there's a free DVC event at Animal Kingdom! So, we'll drive up to Orlando and enjoy that instead.

Whenever we get homeish - Evening chores. Clean up from dinner, load dishwasher, cat food/meds/water, then off to Bedfordshire
As you can see, while my day is full, it's not particularly difficult or stressful. And that's just the way we like it!
