Soulmate

Do you believe that two souls will be one when they cross each others path? At first I didn't believe it. But after meeting one man, this seemed to crossed my head a lot.. Is there such thing as a soulmate? Or is it that we connected because of our similiarities? But you can't help it when you find that someone who loves the same things you do, sees the world like you do and understand what you feel will make us stop and think, is there such thing exist?
