From my early twenties to fifteen years ago I co-habited with various people (I'm now mid sixties). A couple of marriages, then kids, then adult kids, who all gradually left home. Then I was in a semi-detached relationship for nearly ten years, where we'd travel to each other's homes several times a week and every weekend until it struck me that I was dreading yet another weekend of having to accommodate someone else. It didn't help that he was particularly... stringent in his requirements and rigid in his thinking.
I wanted to be free. I found myself in the fortunate position of being able to buy a little house (I'd been renting), so I moved in alone and ended my relationship. I've now lived alone for five years. I thought I would hate it and be lonely but it's quite the opposite.. I even get itchy if I have one of my (now adult) kids staying for more than a couple of days.
I have friends, I have a social life. Money is the biggest stumbling block, but I wfh doing something I love and make enough to get by. I have a dog and live in a beautiful part of the world. I will never live with a man again, although I might just be persuaded to co habit with one of my daughters, should ill health on either side make it necessary.
