Woman has her own happy ending without a SO or a child

To say I'm in a mood would be understated. The world must burn with me.

I want to read a smutty book where the woman ends up with her herself/ friends/ community or even a pet and she's happy about it. She has a good life and she enjoys it.

She can have husbands/boyfriends/girlfriends she dumped. In fact I'd prefer it if she did. I want her to be comfortable/enthusiastic with who she is and her place in life. I'd even be fine with her having a FWB for the intimacy factor but I DO NOT want declarations of love at the end of the book. I DO NOT want an epilogue with her marrying the guy and having his babies.

I mean I literally would be fine if she kills her husband too lol. Make her a serial killer. Make her a FBI agent that kills bad guys and fucks all the handsome men she wants. Think James bond but female.

I want her to be a badass. Financially independent. Confident. Open to new experiences. In fact I want her to chase new experiences.

I don't care if this is fantasy or contemporary but historical likely won't work because autonomy and women weren't best friends in that era.
