Well, I think a man could have written your post, too. You just need to find him!
All of your examples I agree with.
My hubby and I aren't cheerleaders for each other's shows. For the most part, we enjoy the same shows. If I want to watch something and he doesn't or vice versa, the other will do something on their own (I cross-stitch, so it's easy for me to sit on the couch with him while he watches his shows).
We will also pee with the doors open. Pooping, no, but peeing, yes. (We have no kids, just doggies and a kitty, all of which can get the bathroom doors open when we close them anyway).
We eat whenever we want. However, we really only have about a three-hour window during weeknights we can eat, so that answers that question. Sometimes we'll have a "fend for yourself night," and we eat whatever we want. Nothing wrong with healthy foods. I learned last year that healthy foods taste much better than junk. My hubby now agrees
I, too, wear crummy night clothes. Comfort is my main priority here, and my old jammies fit the bill perfect. DH's old jammies are his favorite to sleep in, too. Saturday nights are our nights to get gussied up and go out somewhere nice for dinner, followed maybe by a play, symphony or concert.
The gas, LOL. I've been with DH for 15 years now, and I think we passed gas around each other a few months after meeting. Now we have contests, or we'll do one of those "fluff up the sheets" after an SBD in bed. I don't know. It's human, I suppose, and everyone does it. I find it much harder to hold it in at work or in a restaurant than I do with DH -- and I know he agrees here.
I guess those are my how's and why's.
I understand where you're coming from. My mother is 54, divorced three times, and her view on relationships is very similar to yours. Funny how priorities change over the years. She'd just like to meet someone financially stable, handy around the house, no criminal history, and who wouldn't try to change her sense of independence.
