No, I don't think so. Love is it's own reward and the reason for its own existence, whether or not it's returned or appreciated. In a way, I think it's more sincere because it isn't based on response or reciprocation.
"Your love for her is yours. It belongs to you. She rejects it, but she can't destroy it. She's just missing out on it. What you give, Momo, is yours for good. What you keep is lost forever."
