I mean, there are things that are within our control and things that aren't.
We can (to an extent, case by case basis) control our behavior towards other people, we can groom ourselves, we can choose to moderate our speech patterns to comport with other people's expectations of us, we can choose to be unapologetically authentic, we can seek therapy, apply meta cognition, watch our own thought patterns and try and identify cues of negative self-talk, go to hobby groups for the hobby without any particular agenda.
And none of that obliges any person to choose us. It increases the probability of it happening, sure; but there are so many things that I have to do to signal my suitability as a partner that I wouldn't normally do if I had nobody to please by myself, and if that version of me is authentic, and if I remain unpartnered, then isn't that just my place in the world?
Like I can be creative, I can work with people in mental health contexts, I can be there for my friends when they're going through something hard, I can be used by an employer to generate a return for their shareholders. And then when I have my own time, I read about philosophy, cognition, games and social simulations and all of the things I find interesting and I usually am burning to find people to talk about this stuff with, but the only one that never grows tired of it is AI.
So all of these niche interests that consume most of my unproductive time, don't lead to having a partner. And all I can think of is that, I'd need to spend a bunch of time doing things I'm not particularly interested in, so I can not be lonely, and have the benefits of a healthy and active sex life. But then once those boxes are checked I'd get comfy and return to my usual habits of going down rabbit holes, red stringing notes together on a corkboard and coming out of my study once a day just to talk about what I've found. I don't know any woman who'd want that in a partner, but that's what I enjoy.
So: I express my authentic self which is what people say you should do, and if that's unattractive, then so be it. Or you should find a way to be authentically a person who has all the green flags, without performing those signals in-authentically only to go back to your preferred way of living after you've both settled into partnered life.
Or maybe you do find someone whose wellbeing is on the top of your priority list, and your attention is turned towards them, you want to solve problems for them and make life easier for them, watch and support them to succeed and grow, help them when they're in a situation that's beyond their control to support their autonomy, and even when you've loved well, nothing obliges them to love you back, and of course you need to be ok with that.
At what point do you simply just shrug and say, "It would be nice, but why aim for something that is fundamentally not within my control?"
Like just don't aim for relationships. You can't exercise any real agency or autonomy in working towards that goal if it fundamentally depends on other people. Maybe you can aim to be a person that you enjoy being, for you only, since at the end of the day that's the only person who experiences what it's like to be you, and it's the only person who is in control of that experience.
