Someone for everyone?

Just wondering if it's true that each person has the potential to find his or her "one and only" someday (and by this I don't mean "soulmate"...I just mean a person that you truly love and click with and want to spend the rest of your life with...and I recognize the fact that there are probably several people with whom you can be truly happy). Are there people who are simply meant to be alone and there's nobody out there for them? Or do most relationships amount to just finding somebody who you can get along with and trying to get true love from that?

Any thoughts?

We love out of fear
We fear because we think
We think because we dont want to die
We dont want to die because we were created
We were created for
