Soulmates? True love? One person meant for everyone?

I'm curious to see what everyone thinks. Is there one person out there that is your soulmate? Is that the search of a life time and is true love real? Or can someone have miltiple loves in a lifetime or multiple soulmates, depending on your stage of life.

Example: You find the person that you believe is your soulmate.

You get married, or say vows or any sort, start a family, love them to death. Then a tragedy happens, they pass. Then you mourn for years and years but then you find another love. You guys live a life full of love together and grow old then pass together. Who do you meet up with? Your first love or your second? Or is there only one?
