When you meet the other half of your soul, you will understand why all the others let you go. When you meet the one who deserves your heart, you'll understand why things didnt work out with everyone else.

Keep in mind here that there may not only be "one" person for you in your life?
 Relationships evolve and change, and sometimes you are meant to be with many 
different people along the way to help grow in this journey. There will always be 
different states of personal growth. The key is happiness. If you have found one 
person to grow with you along that journey, that means both have a level of understanding 
of what the other requires. But if you need more than one person to help make this happen
, there is certainly nothing wrong with that and there are many reasons that is necessary 
from a soul perspective.
