I tore my miniscus I wanna say 10 years ago, and the orthopedic specialist I saw said that they don't repair menisci "at your age." The doctor looked to be 10 years older than I was. The knee did stop hurting eventually and the knee feels as fine as it can with a little arthritis. So, you may not need surgery, depending on how bad the tear is.

Have you considered dating women? They're generally nicer than men. (Yeah, me neither.) It's good to take a break now and then. Sorry your dating luck has been so bad.
