关键她是我媳妇毕竟他是我老头
[guān jiàn tā shì wŏ xí fù bì jìng tā shì wŏ lăo tóu]
'The Key Thing Is That She Is My Wife After All And He Is My Old Man.' It indicates acknowledging the reality of relationships (romantic/spousal) regardless of personal wishes or emotions. There may also be a hint of cultural norms around traditional familial bonds here too.
