My boyfriend covets my high dowry but refuses to give me any gifts, hoping to get away with nothing; my brother-in-law cheats on me and commits domestic violence, and uses his children as a shield. Both scumbags are equally selfish and shameless. My sister and I teamed up to fight back, causing them to fight. We lost both people and money, and at the same time, we were ruined and suffered a large-scale social death.
