I'm a bit late to the party but your post reminded me of another user who hasn't been on here for some time afaik. He'd been single for 9 years and was convinced he'd never have another partner. Obviously he then did find another partner - if the ending wasn't uplifting I probably wouldn't mention it :D Don't know if that relationship worked out, but just by the by.
Neither my partner nor I have a car - though we both have driving licences we both hate cars and driving. It's great being with him as things feel equal and we both happily take public transport - no arguments about having to wait around, or about one of us always having to drive, and no endless droning on about cars. A huge plus point in my opinion. (We also like to look at interesting architecture and would happily do a baroque church tour.)
I have been called ugly plenty of times in my life and know this is something you have to be realistic about. I got a nose job in my 40s for health reasons and have not had any such comments/jokes since; people are that basic!
My partner is overweight and balding with glasses and terrible teeth from smoking his whole life. I'm 5 foot 9 and he claims to be taller than me but I think we are the same height - great for kissing I must say. His OLD profile featured a single passport photo. I was interested in meeting him as he joked about this photo, and his sense of humour appealed to me. When we met, I was a bit put off at first by his appearance and the smoking, but he has a lovely deep voice, makes me laugh and is original, laid back and creative. He's also very thoughtful and kind. I guess that over time, I came to associate his attractive character with his looks, or maybe I just saw what was attractive about his looks as I got to know him. Plus he got his teeth fixed haha. In any case, I find him very attractive now. He also cooks for me, which I love after 20 years of cooking for my ex!
I agree that OLD is not the best place to find a partner if you're objectively unattractive, but it is one of many places you might find someone. Why give it up entirely? You don't have to sit there waiting for replies. Just leave the profile up, go out and do other stuff, and maybe you'll get a pleasant surprise, maybe not.
Could you do something to work on your confidence? A lack of confidence can be very unattractive to me, especially if I (even remotely) suspect that the man might have incel, woman-blaming tendencies. Just too dangerous to take the risk.
