I heard someone talk about the Love.

If we had real love with someone, Someday ,they will know.
BUT, why?
I didn't get it.
I try to have real love with someone just One so i never do it before.
But the result is make me hurt.
I don't wanna known about love anymore.
I don't care,if everybody think about me like
" I don't have the heart and feeling"
I don't know,I wanna have it for what?
Coz when i had it, i get hurt.
