what is marriage means?

compromise? pain? or lost self?

I can not say how bad thing the girl did because the trigger lead to her dilemma is her husband cheating. She disappears on their fifth anniversary. The only suspect is her husband. She plans to kill self when everything goes to the end but she changes her mind. The plan goes well firstly. Her husband became the only suspect and he admitted cheating among the public. However, things going is out of her control……

At the end of the movie, She came back to the family and pretended nothing happened. Her husband found out her plan but decided keep silence.

what is marriage? why two people who loved each other treated as enemy? Are there “Gone Girls” living around us, maybe neighbors who living in next door, maybe strangers who are passing at train station.
