I'm 25 and have never been in a serious relationship. In fact, the only time that I haven't been single was for two-ish months when I was 15. I'll go on a dates and hangout with someone for a month or so every 2-3 years but nothing ever comes out of. That's either bc they don't want anything serious or we just don't vibe together. To put the final nail in my coffin, I don't take dating apps seriously enough to find anything worth it on there too.
It can be lonely, and I find myself occasionally doubting my worth to the world around me... But then I talk to people who are in relationships and hear the shit they have to deal with, and it's like an instant cure to all loneliness and self doubt LOL.
I also just enjoy my time alone to be honest. I also lovvve love love having the whole bed to myself and my cat (he takes up enough room as is bc he loves to lay horizontally haha). I, along with everyone else who has ever existed, have problems that I want to work out in my life before I go out and actively search for a partner.
When I need company, I have my friends to pour my love onto! I spend a lot of time with them doing things that are fulfilling such as community work, learning crafts, watching movies and discussing them.
I will always save space in my heart to finding someone I love romantically, but for now I am focusing on having fun, building a good friend group, taking care of my mind/body/soul. I've accepted that the romance will come when I am ready for it.
