When a couple had lived the entire married life under extreme mental pain, agony, and suffering that would not make it impossible for them to remain together could fall within the broad definition of mental cruelty.
Mental cruelty is basically a mental state. For a long time, one spouse’s tremendous grief, disappointment, and frustration caused by the actions of the other might escalate to mental cruelty. It can also include repeated abominable behavior, deliberate neglect, indifference, or a complete departure from the typical standard of conjugal friendliness that harms mental health or provides sadistic enjoyment.
The entire married life should be examined, and a few isolated incidents over a period of years do not constitute cruelty. When a relationship has deteriorated to the point where the wronged party finds it extremely difficult to live with the other party due to the acts and behavior of a spouse, it may amount to mental cruelty.
After a long time of continuous separation, it is reasonable to conclude that the marriage bond is irreparably damaged. Under such circumstances, despite having a legal relationship, the marriage becomes fiction. The law in such instances does not serve the sanctity of marriage by refusing to sever that relationship; on the contrary, it displays scant consideration for the parties’ feelings and emotions. It may lead to mental cruelty in such situations.
