I think they exist in the world. Not just romantically. I think in life you will find a soul mate. There will be someone that just connects with you like no one else will and you will know at that point that they are your soul mate. Having a soul mates isn't just a typical thing they are rare but at some point in life you will find one I have. This person isn't just your "other", well I mean It could be your sibling, a teacher, a person you are dating, whoever. Some people will not know the time they have one but you mite, I mean you mite?
look all I am trying to say is that they could be anyone that you have ever known or will know at some point in your life.
