What makes you happy?
This, really. I'm mid 40s, single, live on my own, am child free. It's not exactly by choice. I would have preferred to meet a lovely man, settle down and have kids. But I didn't want children in the abstract - I wanted to have them with the right person. Since that didn't happen, I remain child free. I now look at the international situation and realise this is not a bad thing. Between Brexit, climate change and the rise of the far right, we're screwed. I worry about me and I worry about the planet, but I don't have descendants to worry about.
It's hard to say the ways in which I take advantage of my situation, because I just do what I do. Horses are my main thing (turn that into a pun if you like). This means I don't have spare cash. And in fact I screwed my career up over a decade ago for the sake of a man. It's my one real regret and now I make choices for me. It's made me wary of partnerships because they're often not really partnerships and someone can take advantage of your trust and screw you over.
So, I have my horse and other people's horses that I'm involved with. I live in a small, rural community, because it's easier to have horses here. It's also easier to be connected. I'm involved with other people's children and I am the cool mad, honorary auntie. I enjoy this. I joined a book club and through this met a friend into music. She persuaded me to sing. Through this I joined music and singing groups and now I know lots of people. I do occasionally meet single men my age or thereabouts. Maybe one day one of them will become a companion. I'd like the option of nights together, emotional and physical companionship. I don't know if I want to live with anyone.
It's cool, I enjoy it. But, I am a loner by nature. If you're not, you might want different things and be looking for other adjustments.
