The Mystery of a Soul mate..

I was 16 when I thought I had found my love, my man, my soulmate. It's been such a long journey since, having found so many soulmates, different in so many ways. I wonder today whether it is possible to ever crown anyone with this deep meaning title. The soulmate at 16 was the naive kid next door, the one at 18 was a rocker, the one at 21 was a thinker. Mates for the same soul? How do I know at 25 that the mate I choose now will change with me the way I change in the very many years? And if he dosnt, how will he still remain my soul mate? Can I choose my soul mate today and know that we will still be the best suited mates for each other over the next 50 years, when we will earn our living diffently, like and dislike different people, face differnet circumtances, read and follow different philosophies, argue and make up unendingly. Will we still be soulmates?
