I don't mean to give you unrequested advice so apologies if I come across as dismissive of your experience. I just feel like I can add some points that people in your situation might benefit from.

And that is to not chase love in itself. I found that as I got older I also accepted that I would grow old without a romantic relationship. Though I did invest time in my friendship relationships, and that did work.

While being somewhat saddened by it, I accepted that the chances of me finding love through dating apps was low, in particular because I don't want to have kids, which obviously is a deal-breaker for many people. So my approach there was to just try to enjoy the moment without expectations and without judgement. If I got a match I'd try to have a fun conversation, if it was fun I'd try to set up a date, and if that was fun I'd keep it going. Just going for having an enjoyable time at that moment without expectations. It made even the dates that weren't going anywhere long term enjoyable experiences, with the occasional opportunity for physical intimacy with someone who was on the same page about expectations. I could have lived like that but just got plain lucky this year I think. For me it still feels amazing to have happened so I'm not going to type lies and say it will happen for everyone. But I went into this relationship with no expectations either so regardless of what happens in the future I will treasure what is happening now, as I'm a relationship with the most amazing woman who adores aspects of me that would often be things other dates told me made me seem immature and obsessive.

So, you and people that relate to you, I genuinely wish you happiness and good things. In all aspects of life. But please don't give up on meeting new people if you can, you might make someone else happy just by existing. Or if not you could at least give them a nice date.
