Every man is paired with a woman to procreate and share a life together. But grammatically speaking, is the singular noun "woman" a fact or merely a myth? With the interaction of neurotransmitters in man's body, the answer might lean more on the latter.
In a romanticist's point of view, a relationship blooms when a man falls in love with a woman, and vice versa. With love, the couple can move mountains, doing the best they can to keep the fire burning, to accept his partner for who she is wholeheartedly, and to build a life as husband and wife forever. For hopeless romantics, love is the essential force of the relationship. The man and the woman are bound to each other, perhaps even in the afterlife.
But in the view of science, this is all debunked.
And in the view of realists, this is all bullshit.
