This movie doesn't make sense to a great extent. If a divorce can happen just because of outburst of an emotion then marriages will hardly succeed! Infact if marriage is such a loose relationship then it just lost it's meaning.
Weather it is happy or sad, married couples should live through them together. Obviously a lot of things happen in between a husband and wife, it's not always a good journey. A man and woman both are ofcourse imperfect, they are often opposite of eachother and it's upto them how they better themselves and life for each other. According to an old survey, 95% of married couples face though times during the first 3years of their journey and then the life changes. Life changes because then they understand each other and learn how to keep each other happy!
This movie is absolute mess! I see so many positive comments on this movie, obviously this shows current generation just thinks logically and practically. They do not understand the promises that are made during the marriage, they do not understand the value of "marriage".
A "slap" is an outburst that happens when someone is so disappointed that they lose conscious temporary. Even a mother slaps her kids, that doesn't mean kids go to the court. Having said that, obviously it's imperfection which leads to that, ofcourse if man or mother is a psycho then they deserve to get separated. But if they are normal, then they deserve to figure out their mistakes and change eventually.
