Sympathetic Resonance
When love is at a certain stage of awakening between two people, their frequency rates reach attunement, so they become more compatible and resonate together. Unfortunately this state of resonance does not maintain itself without continued effort on the part of the couple in love. If the woman becomes dowdy or irritable through stress, or the man becomes inconsiderate or boorish, their frequencies become less finely attuned and gradually alter, so they are no longer as compatible and may even become antipathetic.
