The other comments are solid.
I didn't meet my wife until I was 32. We've been together for 9ish years now and have had one major argument. It has otherwise been amazing and we compliment each other well.
At 25 I wouldn't have even been ready to "settle down" so to say, in fact I probably didn't get there mentally until 28 and still...life is a regular learning thing.
At 28 I had gone on a random smattering of dates that really made me realize what I do and don't like. I had decided I'd be fine being alone as well, which wasn't terrible. I had volunteer opportunities, a good job, and some local meetups I enjoyed.
I say all this to mean, don't give up but also like...the biggest thing for me was to hone what I wanted or didn't want. I am pedantic and picky as fuck, and I had hit a point where I was OK not finding someone but...that was exactly when that person was found.
My advice, you gotta do you, you need to enjoy life first. I don't care if it's a video game or a local pub with a specific dish or a park with a nice view. Figure out that list and then seize it at every turn, then hone it and expand it and sharpen it.
