I think I have ruined my life...?

I've been in and out of several long term relationships over the years but have become more cynical about ever finding a mate that is compatible....I basically have stopped searching and its been 1 year since I have dated anyone. I'm getting older...never married , no kids and now feel like I've wasted my life here on earth....I think now I am too set in my ways...I have no friends now because they all married ...alls I do is work and come home to nothing...total emptiness....so, is this my destiny? I don't even have desire to search anymore....pathetic, isn't it?
