to love or be loved?

i vaguely remember a line from a movie/tv show i watched quite a number of years ago. goes something like that:
"when u love someone,u give all u have...and u dun expect the person to repay you. and hopefully,that person loves you just as much...and that person would give you all he has..and he won't expect you to repay him. that is why it is a blessing to be loved...and a challenge to love."

so basically,it's better to be loved than to love? at least i think that's what the above line is trying to say...

well...i start to wonder...what if u love someone who doesn't love you back? like when i had a major crush on that guy some years ago...and yet he was totally oblivious to my presence...or what if you love someone...and that someone loves u back...but doesn't love you enough? or what if u love someone but that someone not only dun love you..but hates u? how bad is that gonna be?

i reflect upon all the things i've done that i can remember..and i really wonder to myself how many times had i hurt someone who loved me because i was oblivious to that person's presence, because i din love that person enough..or even worse,hated a person who loved me?

not talking abt just BGR...i mean love in general. like between me and my mum, i feel that i dun love her enough when i was younger...trying to compensate for it now. or between me and my brother...when i am sometimes oblivious to his presence until i needed help from him.or between me and a friend in sec school...she's nice but becos i can't stand her due to an incident,i nearly hated her...

suddenly i feel like i came in number one on the top 10 list for the lousiest human beings on this planet.

i always thought i am an average girl. below average looks, below average figure, slightly above average grades,more or less average personality...in my life,i try to make as many people in my life happy as possible,cos i derive happiness from the people around me. after reflecting, perhaps i am just a pain in the ass most of the time.

or rather,i am a pain in many peoples' asses. with my constant nagging and whining, who wouldn't hate me?
so maybe i fall into category three in many peoples' life? when i love them but they dun love me...and even hate me?

so if u take a chance and love someone,u might end up
a)be loved in return
b)the person not knowing u love him/her
c)be loved in return but at a lesser magnitude
d)be hated by the person u love

one in 4 chance for a perfectly happy ending...lousy odds eh?
but we continue to love people with all our hearts and souls, hoping to have them love us as much in return. why?

because when we are loved in return,the blissful feeling we get erases all the pain we endured from the other three possible endings...??

now that's the question i'll bring with me to sleep tonight...
