So close...yet miles apart!

Its so strange how dependent can we be on relationships. Relationships with friends, family & even at times strangers. Yes, we build relationships with strangers which after a certain period of time, becomes our life.Thats when we fall in love!
Be it friendship or love, we think that we know someone so well over the years that we can see through him, and suddenly one fine day we are forced to come out of the illusion. We realize "This is not the person fell in love with/I was friends with!"
What does one do then...how does one deal with such kind of a situation????
Sometimes we part our ways; sometimes we try & work around the situation,make some compromises & then everything is kind of back to what it was earlier. Then suddenly in the middle of the night,the one you love just walks away leavig an SMS behind "there's no spice left in our relationship!" Whom do you blame then, yourself or the one who walked away? Life comes to standstill...rather it seems like the world around you has come to standstill....!!!!!!
You try to gather all the broken pieces and with the will to start all over again...the question arises..WHAT NEXT????
Being in a very steady & strong relationship since the last 5 years, such kind of a situation is really very dreadful. But,now, this thought would never go off my mind "So close...yet miles apart!"
