12. To constitute cruelty, the conduct complained of should be ‘grave and weighty’ so as to come to the conclusion that the petitioner spouse cannot be reasonably expected to live with the other spouse. It must be something more serious than ‘ordinary wear and tear of married life’. The conduct, taking into consideration the circumstances and background has to be examined to reach the conclusion whether the conduct complained of amounts to cruelty in the matrimonial law. Conduct has to be considered, as noted above, in the background of several factors such as social status of parties, their education, physical and mental conditions, customs and traditions. It is difficult to lay down a precise definition or to give exhaustive description of the circumstances, which would constitute cruelty. It must be of the type as to satisfy the conscience of the Court that the relationship between the parties had deteriorated to such an extent due to the conduct of the other spouse that it would be impossible for them to live together without mental agony, torture or distress, to entitle the complaining spouse to secure divorce. Physical violence is not absolutely essential to constitute cruelty and a consistent course of conduct inflicting immeasurable mental agony and torture may well constitute cruelty within the meaning of Section 10 of the Act. Mental cruelty may consist of verbal abuses and insults by using filthy and abusive language leading to constant disturbance of mental peace of the other party.
