Stages of love are compared to seasons of the year:
Spring is new & blooming love (warming up to someone), because it’s when plants start to grow again, allowing animals to eat more than during the winter. The additional food and warmth during this time lowers animal hostility, and is the most common season for mating because they have summer and fall to gather nutrients for the fetus.
Summer is considered the more slow and easy, but still good part of a relationship, because summer is the warmest (most loving) part of the year. Losing love during the summer season is unexpected because the relationship has lasted awhile and doesn’t have much hostility.
Autumn (fall) is considered the beginning of ‘falling’ apart. In autumn food becomes more scarce and the cold (feelings of distance) starts to set in.
Winter signifies being single. During this very cold (lonely) time, everything (love) is scarce. During this time people are most reminiscent of summer and spring (loving warmth).
