@crochetmonkey74 - welcome to the best kept secret ever! Solo life for me is unapologetic, joyful freedom with no compromises. You can do anything you want without having to consider anyone else - whether that is dramatic changes or just small things, or both.
The most life-changing part of choosing lifelong singlehood (at 28 after two excellent relationships, and I'm approaching 39 now) for me is living on my own timetable rather than society's normal one - on work days I'm not actually with clients, I get up about 10/11am, feed the cats, journal and read for a couple of hours, then get ready and head out to my studio for about 1/2pm. Work till about 8, with a break to wander by the river, and then home for dinner and more reading, and bed between 2 and 4am. There is absolutely no way I could have done this with a partner as I'd never see them! And the risk of self employment was mine alone, so yes, there's no backup support but there's also no one I'm responsible for financially. Except the cats and their extortionate food 😂
Days off are endlessly different depending on what I feel like, and I've also been able to choose to be much more involved with caring for my Gran along with Mum who does the bulk of it, while the rest of the family runs around partners and children instead.
The other small but very satisfying thing about solo life is how excited everyone always is when they see the inside of my home and studio - and my friends with partners, even the lovely ones I know well & am friends with too, always say they wish they had free rein to decorate just for them, even down to ridiculous bedding choices.
As a previous poster said, I've made a life I don't need a holiday from and it is glorious - and so much more fulfilling to me than when I was with either partner, even tho they were lovely men and I am still friends with them both.
I'd also massively recommend looking up Bella DePaulo's work, she researches single at heart people and has written some amazing books and articles about it too.
