well, i say no one knows exactly what the love really is. because for everyone their feels it in a different way according to his/her nature. there is no exact definition of true love we can cater.

but,

i say, do love for your own self not for the other person. if you truly love someone then love him with this reason that you want to love him/her. if you do it in that way, you will never compare the return. The strongest love in the world is one way love. because you have all the right on your love which way and how you do that. and you will be keep loving until your last breath no matter the other person loves you in return or not. because true love never ends. what ends is likes and wants. and love is beyond these self desires.

that's how i see the relationship.
