I think that in life it is extremely rare to ultimately end up with the one we loved the most...or the one we love the longest. Successful relationships aren't always only about love, so many other factors like timing, finances, geography come into play.

This said....I believe that if we focus on our own personal goals, whilst building a life we can be proud of, then we attract like minded others...others who could very possibly be a version of 'The One'. But as mentioned above...don't give yourself over in the hope of being made happy by another person, it takes a lot of work from both sides for relationships to progress to a place of health and happiness. My best advice when entering into any type of romantic relationship is that its ok to be on the same highway, but in separate lanes...keeping a margin of autonomy and a sense of self.
