the rationale of love

i often heard people say "love has no boundaries"and does not follow the normal route always. a saying which appeared absurd then. But an incident, changed my thoughts and made me feel that the world is not wrong is saying that......
I remember my friend, saahil, a jovial guy and a caring friend. One who feared the sight of violence(would even puke on seeing bloods and i had to pacify him)....no one ever thought that he can do something so daring....consume poison..
but love made him do so
Let me tell here what happened actually. This guy had a very good track record in academics and sports in school and had lots of(actually loads of) girls falling for him. Once when i asked him"tu itna bhaw kyun kha raha hain", he replied "i don't feel anything"!! Strange that a guy of 20 years doesn't feel anyhting .
Anyways, it was two days for bhai duj, and my parents had gone to his house to invite him(he also was my rakhi bhai). Mumma and papa returned that night and said they would not dine. We were ok with it,as we thought they were tired. But then as i was about to go to sleep, mumma told me "i hardly think that you would be able to put tika to saahil ever again in your lifetime". A little confused i asked her the reason for this disgusting statement. She tole me"he committed suicide".
The story behind this goes like this...this guy had a strange fate which made him love a girl whom he cound never get married to. The girl was his aunt, chachi. When his love for her reached its zenith and he got an idea that it is going to be an endless journey, he decided to halt. Cease to exist in this world for everyone. He did it, and consumed poison. His relatives immediately took him to the hospital but poor fellow died on the way. On knowing the reason, his father decided not to mourn his dead and was happy as someone who would bring disgrace to the family was dead. He said "its good he did my work himself".
But till today, I try to get an answer to this question "what was his fault?". Was it that he loved a girl or he listened to his heart?.....
Why does it happen that one who loves looses most of the time. We are all inspired by the stories of Romeo-Juliet, Heer-Ranjha, Laila-Majnu....but one thing common to them is..
"THEY NEVER WERE UNITED"
Is this the rationale of love that you love someone and then you don't get him/her and end up loosing your life? I support Saahil, in whatever he did. He loved, loved right from the heart and lived with that and died with it.
I also pray that no innocent souls in this world ever get the fate like saahils.
BEST OF LUCK GUYS.....
