I do not believe in Soul Mates myself personally....however...
If there were such a thing, one could only know that after having spent their lives together...in my opinion...and therefore it disqualifies the term "I have MET my soulmate"...
The media plays a huge part in regalling celebrities lives....how many have MET and married their "soulmates" only to be divorced some months down the line...well how does that happen if you met your soulmate?
Like i said, if there were such a thing as a soulmate, then one could only know that after having spent a "lifetime" with their partner...and in those years spent together through thick and thin, good and bad know that they had a "soulmate" who stood by them...
