What does it mean to rob a marriage?

Marriage is marriage, and robbing money is doomed misfortune and twists and turns. Snatching marriage is a conflict after the long-term relationship between husband and wife is uncoordinated and the contradictions intensify. If the adjustment is timely, the marriage will not break down. Perhaps through this disaster, the two will become more mature and their marriage feelings will be more stable.

The second explanation:

Marriage robbery is robbing the bride or groom when others get married.
