Or meeting people through work (though I wouldn't recommend that one generally on the basis of “don't shit where you eat”, I've seen it work for others).
Or through hobbies (I know a few people who have found partners in the trail running community, for instance).
Or just being happy single. Or, at least, no less happy than you feel you'd be with a partner. Take it from me, someone who is content to be an honorary mad cat lady, it can be a decent life.
Many don't seem able to accept that life can be fulfilling this way, and every now & than they try to fix me by trying to nag me into the dating game. I'm not against dating, or finding a partner, I just don't care for it enough to make much effort, I'm not willing to lie about that or pretend to be someone I'm not more generally, and I doubt potential partners will find that very appealing!
Many don't seem able to accept that life can be fulfilling this way, and feel like lesser people because they are single, which is possibly why people often assume my PoV is something I'm pretending about. And some just want the physical side of things, and see dating/relationships as a gateway to that, and they again see me as odd (or lying) when I say I can happily live without it.
