Soulmate

"Why doesn't long for someone to hold
Who knows how to love you without being told
Somebody tell me why i'm on my own
If there's a soulmate for everyone."

is a piece of lyric from Natasha Beddingfield's song titled soulmate. I had been thinking about these lines over the week. What if my soulmate had gone away. Is there a second soulmate for me?
