How can I come to terms with being alone for the rest of my life?

I think its time i accepted that as a real possibility. Im a great person, but thats it. I have good qualities, im funny, sweet, quite intelligent and fun to be around but not very god looking and a bit fat. the thing is, although i have some good qualities there are plenty of people who are better. so i dont blame women for choosing the better option. im a real candidate for dying alone, unnatractive, shy, a little wierd and generally unlucky. there are, sadly, many people who die alone. 20% of people in the uk dont ever get married. now some of them will be like that by choice, some will be disabled severly, some will lve with a partner but never marry them but i think a lot will be guys like me, guys who either never tried to find love or guys who tried their best but their best wasnt good enough. i intend to try my best to find love, online, thoguh friends and ill be as social as possible and see relationship councillors and escorts and maybe order a thai bride, anything but if all that fails, how can i come to terms with living a life alone. i know ill have friends, and i could maybe adopt children (i love kids), but its not the same as actually falling in love and having someone love you back. im not sure i would want to live without a wife
