Maybe its not necessarily this guy who is giving you these feelings of love........like from the film serendipity the quote is....or something like this:

"if you want to be with this new person, maybe its not THAT person but just the fact you want to be somewhere ELSE"

Maybe you are searching for this true love that dosent excist now or ever with your current boyfriend........some people settle for a "nice" happy life, its whether you want that, or choose to leave and go in search of your ultimate dream ya know...
