The One

Many ppl spend their whole life to find " the one "  that will make them complete . Yet there're still some others don't believe in  " the one " . 
I make not sure if  we should  consider it as a romantic notion  ~   One person out there who will make you complete  ,whole and happy  !
Call me the worst optimist  ~ I often think this is total co-dependent behavior and it will only lead to sadness and frustration . 
Yup  there are 6.6 billion ppl in the world but it's still not easy to find that special someone who will make a great life long companion and share your dreams . 
 Is life just one big race to find " the one " ?  And how do you know if you have found " the one" ?  Or shall we stop looking and find " the one " in ourselves ?  
Relationships like everything in life have a life span  ~  they end  begin again and the whole cycle repeats itself over and over again . Some are only temporary  some are for a few months or years and some are even just for a nite  ~  the only long term relationship would last forever is with your own self .
