I don't think it's too late at 50. However, I have noticed that as I grow older, the thought of starting over, if this relationship I'm in now fails or he dies, isn't all that attractive. I think that when you're younger you actively seek relationships at least partly because you are expected to, but now, I'd be fine not being in one. I can stand on my own two legs, manage my own life just fine. It would be a bit lonely at times (I know it is because I've been a single parent before, and that's not always easy), but there are many positive aspects of single life too. If I should start over it better be someone really damn special, because I'm over random relationships for the sake of relationships.
