Yes True Love exists. Yes platonic love exists. Love without gain, without logic, without phisical intimacy, exists. Otherwise how can we explain love between partners where one remains in total paralysis for years, love for one who  has died years ago ? ……. Thats the capacity of human heart. Platonic attachment exists but it must be kept in limits where it is reciprocal only !  One sided platonic love is a somewhat hallucination of heart without any gains. It does not fulfil you, it does not enrich you. You are capable of it as a human but it’s pointless. If a person has never loved you and never will then there is no point in allowing that person to linger in your heart, your mind. It is time to move on. Remember there is always ‘someone’ who will love you truely. Find that person !
