Realising that someone has stopped loving you is a thoroughly frightening experience.
But it is an experience most of us meet at least once or twice in life. What is astonishing here is the astonishment itself: people do not believe it can happen to them.
Internalise this. Romantic love, exactly like a house built from a kit, is a human creation. If it can be built, it can also be dismantled.
But that is not the most painful part. Usually, when you share the sudden separation tearfully with your friends, they comfort you and say: it is not you. Obviously you were wonderful. It is him. It is his loss.
There is a chance they are lying.
Because when they leave you, they leave you because of you. They leave you because you were not good enough. They leave you because they believe it is possible to find someone better than you.
That does not mean you should cast doubt on your entire existence. But a small accounting of the soul will not hurt, or at least some symbolic inspection of the premises.
And the most frightening thing? You think you will fall apart, and in most cases you do not fall apart. You discover you can manage alone. You may not want to be alone, but you are definitely capable of it. Not always happy and calm, but surviving.
And this whole manifesto comes to say something surprising: invest in your relationship. Now. Give attention to the other person. Observe them. Take an interest in them. Think about how to make them happy.
Because if separation is a scenario that is always realistic, then it is the most human and the most legitimate thing in the world to try to prevent it.
Never be ashamed of the fact that you are fighting for a relationship. It means you understand something very true about the human psyche.
And I salute you for it.
