All plants are not the same.
Some plants need very little sunlight and water to thrive, while others need a lot of sunlight, water and extra care to fluorish.
Some withered plants can be revived instantly, while others take time and lots of TLC to return to full health.
Love in human relationships is rather like a plant that needs to be cherished and nurtured, according to the individual's needs, otherwise it will wither away.
The good news is while love can appear to wither away it can never die as that is impossible.
Just keep watering and feeding that plant and watch it blossom.
