Humans are like plants.. When a plant reaches a certain point it needs a bee or another pollinator to come and pollinate it's flower.. If the pollinator does not come and do it's work on the plant the plant will never produce the fruit...

Where love is concerned you need to strike while the Iron is hot.. Failure to act upon love will see that love die before it is ever given an opportunity to ripen and mature..

People who say that if it is true love then it will last forever are talking about God like perfection.. Human beings are not Gods and thus their love is not perfect, nor can it last forever uncultivated.. Human love needs work, it needs continual affection and care.. It need action to reach it's best condition..

Human love that is neglected, fades and dies..
