At the end of the day a Relationship triumphs. You can spend a thousand years fathoming the unseen intricacies and the misunderstood squabbles and whines. But you have to understand that in the end, when the end comes, it is simply because there is nothing left in you for the relationship to take. So it decides to leave you.
I treat it as an entity. You, me and relationship-three entities. It takes the best of you and your beloved, and what is left in the end are nagging, groveling, griping, selfish, hurtful, spiteful and nasty people while Mr Relationship attains sainthood –of all that was good.
A relationship takes away so much of good in you, that you are left with nothing but regret, despise and a whole load of other debasing and damaging thoughts and foreclosures which sometimes (subjectively speaking) might drown you into the murky waters of intro and retrospection.
I hope you make it to the shore.
