Why people so focused on their relationship when their young

I read 1 of my friend's blog,

because of you, i found myself
because of you existence, i deeply fall in love with u
because of your smile, will let me happy forever
......
.....

why do u LEAVE ME? what did I do wrong?
can u please tell me?

@#$!*! Oh my god, are they watch too much Taiwanese movie?
if also, please have your own mind that what kind of things for you to have and speak about LOVE and RELATIONSHIP?

For girls, yes, they might be easy FALL in love in relationship because they need to admit sometimes guys mouth are too sweet that u will fall in love in him. but think deeply is that what kind of things you have to maintain your personal things especially love? Money also a problem still wanna say about love? think about your own stomach and think about your future is much more better

But for guys, when they break in love,

usually this is what they say,

I don't have anything except YOU
I can't leave without YOU
In this world i only love YOU only, why do you leave me?
.........
........

Still have more of it, but this is only some of the common words that a guy when breaks up.
BULLSHIT man, BULLSHIT. God gives u a brain to think about of your life, but not only think about love and relationship. forethought yes, love is consider on your life. but for TEENAGERS, 80% of them is fall in the river of love, don't care about the world outside of it, when breaks up, ya, CRY LIKE HELL they only will do, more seriously, commit suicide. !@#$%&*, i don't even know what is slot inside their brain......

Yes, we can have a relationship, but please think a bout your own situation FIRST. duit pun takda, mahu pergi mengurat lagi? then for people in relationship, please bear in mind especially for guys, in our life there are so many of things that can happen, like career, friends, family, charity, and so more, not only relationship is consider inside, but there are so many things. think about it first, usually a man that matured will put their relationship and love on the last. because they will think about that important FIRST than only about personal relationship.

For those in love, think about your future what you want to be, but not think about now how you want to be. for those who is single and still in teenage time, think about your future first only step in the circle of love. because this is a world of reality, not in world of taiwanese movies.
