I don't believe in true love, I think that putting the responsibility on destiny  or the universe is not a good idea. I think that different people are good for us in different time in our lives, and that once we are ready, choosing a good and matching person to live with and love is very important part of our happiness.

I'm incredibly romantic and did massive amount of changes in my life for the sake of love, I truly believe that it's the most important part in my life, However just because i had relationships in the past that ended doesn't meed "i got it wrong" or that "I messed it up". It just that what worked at one point stopped working in another. 

I don't think true love is something we find, I think it's something we create, by putting time and effort and attention into a person we chose to be with.  without working at it, the initial attraction and beginning falling in love feeling will go away entirely, leaving us with that "but what went wrong" feeling. It's funny how we accept maintenances and change in almost every other field in our lives (like our body or our car or the house we live in) but expect love to stay the same and perfect all the time.
