On A Side Note: Empire of Love

I have observed that relationships these days are a lot like empires. They have a rocky to smooth start, then enter into a Golden Age, where love and wisdom fuse and flourish. And finally, it breaks apart due to enemy invaders who corrupt the empire and collapses it from within. Relationships usually start when both man and woman are just getting to know each other. They must adapt to each other before they get even closer. Then once they do, they go into a figurative Golden Age, where love and understanding between them is mutual. This lasts for a couple of years. But suddenly, without warning, an enemy nation comes to corrupt one of the spouses. He or she seduces the other and causes unrest and civil war within the relationship. They couple's bond becomes weak and is severed. The empire collapses.
