I think the number of "someones" for any given person depends on how closely that person fits the mainstream of society. People who conform have many possible someones. People who have offbeat interests/views, etc. have fewer possible someones.

I am one of the "offbeat" people. Being a nontraditional woman who doesn't want kids has its disadvantages... I have only met one man who would have met all my criteria for "my someone" - except that he was already married. So that one was out... I have also met someone who met enough of my criteria that we have had an open LTR for many years. Unfortunately, there are a couple of issues that keep him from being, to be cliche, "Mr. Right".

But the way I see it, I can have fun in the meantime, and I'm actually not too worried about meeting "Mr. Right" at this time. I think part of it is because I'm too occupied in looking for a job at this time. I think I need to get my act together in that part of my life before I can even think about a serious relationship.
