When a woman falls in love, she becomes a little fool. Well, naturally, figuratively, in the eyes of this man. She believes. And the attitude to this, to put it mildly, leaves much to be desired ...
When she ceases to love, that is, becomes cool towards him, he begins to see that what she is good, how they could be great ... but she no longer believes.
This story is old, at all places it happens. The question is, who in this case should prove himself? That is, give way.
