When you love somebody, rationality goes out the window. It narrows the scope of vision and you become suspended in a fog of emotion and irrationality. You are exaggerating their positive traits and diminishing their negative traits by having a naive perspective.
So when a man falls out of love he begins to become rational and he will start seeing the traits he hates in you. He will start to come up with reasons not to see you. Even in texting, he will take longer to text back compared to before. Because when a guy falls out of love his emotions go down and his rationality comes up.
When this starts to happen you can’t do anything about it because when a guy falls out of love with you it is not because of the reason he is saying but he just starts making rational decisions.
