Smt. Renuka ji,
"smara" as you know well, is the Imperative Mood, if we take it as the verbal form of स्मृ (Ist. Conjugation) instead of as denoting the kAmadEva. Then, smara garaLa khaNDanaM will mean, "Remember! the neutralisation of poison" and not as you say 'breaking the poison of remembrance'. For this meaning to be read, Jayadeva should have written स्मृति गरळ खण्डनं (smṛti garaḷa khaṇḍanaṃ), imho.
Secondly, it is well known that Jayadeva was a precursor to the वैष्णव-सहजीय cult and, through the invention of the new Radha-Krishna love, Jayadeva was only reiterating the सहजीय philosophy which held that the highest spiritual attainment could be had only through sexual union between man and woman.
The gaudeeya is a branch of vaishnavism. The Brahmavaivartha (BV) Purana is their most sacred scripture. It says that Radha is the most Supreme Godhead of the Universe who resides in gOlOka. She, along with krishna, her lover, are their highest gods. Krishna (& Radha) created vishnu, brahma and siva. Curiously, Ganesha and Parvathy get one full canto of this BV purana, called Ganesha Khanda. Some people firmly believe, Vyasa Maharshi himself composed/wrote this purana also, in Banga Desa, in order to educate the devout people (throughout bharatavarsha) in the correct moral ways of life!
Jayadeva's Ashtapadee describes this Radha-krishna relationship, which includes oral sex as also a scene in which Radha places her foot on krishna's head as part of their love-play. iskconites treasure all these stuff as the sure-shot guide to final liberation. During Jayadeva's times it was more part of an emerging tantric cult with unlimited and free-for-all sex as a method of enlightenment (and Osho caught upon this idea and propagated it, successfully.). Later on this Tantric Cult became popular in Bengal as the Vaishnava Sahajiya Cult. The ruler of Kalinga, in a subsequent period, proscribed Jayadeva and his work from his kingdom, because he felt Jayadeva was a threat to public morality. So, Gita Govindam went into oblivion for some centuries until it was traced again in some other part of the country and brought to light in the 18th. century by the Britishmen ruling our country.
When he enjoyed the good books of the Kalinga king, Jayadeva made the singing of Gita Govinda a daily ritual in the Puri Jagannath Temple and also recruited virgin girls to dance to these songs, before the deity. These dance girls who were called Maharis danced the Mahari dance and Odissi evolved out of this Mahari dance. Jayadeva also institutionalized the Mahari system in all temples of the country, Kalinga. The Devadasi Sampradaya was this Mahari system when it spread outside the Kalinga country.
This kind of Radhe-krishna worship caught on still further north in Bengal, Brindavan, Mathura, etc., areas. The present Brindavan with its krishna, Radha temples and many widows, etc., is only a sad reminder of the erstwhile Radhe-krishna cult and widows trying to emulate the supreme Radha. In Bengal, this bhakti-madness went to the very extreme of devout men observing menstruation (of course, falsely) and the untouchability connected with it etc., in the hope that they had become one with Radha; thanks to the British, this nonsense was exterminated with an iron hand, but some isolated fringe-groups within the very lowest castes, who might have fled the British territory then, may be continuing this madness even now, we don't know!
