 my try

you´re right maybe but the person at  first time when he loves ,he doesnt think that it´s right or wrong or he doesnt wait reponse or in return,Iam not unhappy ,iam not waiting reponse or in retun just I love

You are right maybe but when a person loves, s/he cannot think if it is wrong or right or s/he doesn´t expect a response. Mine is also unresponded, but I am not unhappy, I don´t expect a response, I just love.

Ask karsilikli olmak zorundadir. Karsilikli degilse, adina ask degil "kara sevda" denir.

Kara sevda bir hastaliktir; cabucak atlatmak gerekir.

 Love must be mutual.If it is not,it is not called love.It is called´dark love´.Dark love is a disease,one must get rid of it as soon as possible.

Sounds like F.Nietzsche to me.

edit..

hmmmm... i know this is  a translation, and it´s a translation request, but just want to say something about it. jade_jade´s translation, i think the guy was referring to unconditional love. Loving someone, without expecting something in return.

AlphaF´s translation request, it is not really about love, it is about obsession. There is a big difference with unconditional love, and obsession.

I dont see anything wrong, with loving someone without expecting anything in return. just a thought.

Love does not include any condotions, except that it has to be mutual.....By definition, love must be mutual.

how about a mother´s love to a spiteful son? isn´t the love there one-sided? and if it isn´t mutual, is it wrong for a mother to love a son, just because the son doesn´t love him back?

 That is the unconditional love of a parent to a child, but not all children love their parents in the same way.  Mutual love in my opinion is between two non-related people.
