Looks like my personal life is set to go downwards. After having a "great" birthday, I got bumped with total destruction called "break up." Its so funny that I am writing about it. Its painful knowing that the girl who was in your arms today would be acting as if you are nothing to her from tomorrow onwards. Equally painful to know that the girl who meant so much for you today, you have to consider as if she means nothing to you from tomorrow. First case is something which I cant help and can live with it some time. How can I overcome my own deep heart-felt feelings for her? How can I live in the illusion that I never had anything for her?
I look at her now and see a face so beautiful as it has ever been, and knowing that I cannot kiss her anymore. What I cannot understand is this: how come it affects only me? Does that mean that I am the only one who had been loving her all this while, while she was having just fun with me? May be, I should have realized it long ago, when she always used to complain and put me down saying that she is expecting a prince charming. I thought she was just saying it for fun, but it so turns out that it was a matter of grave importance and grave consequences.
Atleast now, I dont seem to be as fettered as I thought I would be. This might be because she is still with me and not talking about her prince charming a lot. But will I be able to take it in the same poise when I see her clinging onto someone else? Will I be able to bear if she hugs and kisses someone else infront of me?
