When we grow older, we become involved with so many people like sons / daughters/ relatives/ friends that each of us, like a big tree, spread our roots all around us. We depend on them and they depend on us.
The older we get, thicker and longer grow our roots. End of a long relationship cuts off many of these roots from our life. As we are not yet western in our mental make up, these cut off roots really hurt us and our near ones. Its like wearing an old pair of shoes which is not giving you smart look but you are comfortable with them.
Of course there are times when breaking up and starting a new chapter in life is the only solution, but that point should only be reached through deep soul searching and really considering all the fall outs.
But of course this is only my opinion, other wise persons may have different opinion.
Take care. :-)
