How can I truly accept and deal with never getting married?

I truly genuinely absolutely believe there's no hope for me finding someone and ever getting married. As it is I've been single over 20 years. I'm certain I'm not want any girl wants or looks for in a guy & nothing will change my mind on that. My question isn't how to fix that but how can accept it & learn to be ok with and not have it bother me so much? And how can fulfill myself as a single person the rest of my life?
