Being able to interact with my kids in my home without being demeaned, mocked, or undermined. (Not to say it never happens, but it isn't a constant.)
Being able to prepare and consume food that I enjoy without hearing how disgusting it is or how miserly or puritanical I am. (I didn't purchase or eat bell peppers for over 10 years because he wouldn't STFU about them and behaved as if I was force-feeding them to him if I so much as ordered them FOR MYSELF.)
My ex smokes, drinks, and has appallingly poor personal hygiene. He also thinks it's hysterical to let the farts fly as they will, and they do frequently. (Yes, it can be funny. Yes, the kids and I both do it. But being asked not to and continuing to do it is just not cool!)
I HAVE MY OWN SPACE.
Nobody gives me a guilt trip for expecting to enjoy and have some control over my own sex life.
Wow --- just realized that most of these don't have to do with being a parent or being single -- they all have to do with my ex.
