Alert! A new Dasa period can break a Relationship

Star matching and chart matching determine the attraction between a boy and a girl. Sometimes a change in the dasa period of a boy or a girl breaks the relationship.
For example, a boy loves a girl very much in his sukra dasa. He fights with the families and marries that girl. After some time, his dasa changes, and now he is in Surya dasa. If that is good for the girl, then the relationship will continue, or it will break.
It is similar to when two close friends separate for reasons like education, jobs, or foreign opportunities. This is because of the dasa change. And no parihara can bring them close again.
