"If I love you, what does that matter to you!"
Johann Wolfgang von Goethe
This is a very violent form of unilateral love, and I can understand it because I once, temporarily fortunately, experienced this. :) This is a type of love which is irrespective of the response of the lover... but it would be more appropriate to say that it is mostly stimulated by a lack of response of love. But since the lover is reluctant to let go of the feeling of love, he/she retains this emotion without expecting or desiring any reciprocity. A love which has no desire to be reciprocated seems a bit unnatural to me, almost inhuman perhaps... it's like loving a statue or a painting. Suppose someone says to you, "I'll love you no matter what you do! I'll love you even if you hate me!"... What can you do with such a stubborn lover? Uhh... gives me the shivers!
