The ancient Greeks called this type of love “madness from the gods.” Love-mania is considered a punishment. This love is an obsession. She makes a man in love suffer. Write poetry. Don’t eat or sleep. In the short term, it is acceptable in healthy relationships, especially in early adolescence.
If it drags on, this indicates a craving for unhealthy relationships, impoverishment of the personality and requires an appeal to a specialist. Especially if love-mania brings suffering to the object of passion. Then the “lover” strives to be near his beloved all the time, tries to control him, experiences insane passion and jealousy.
