Triggers
For men the strongest trigger is sexual infidelity and with women the strongest trigger is emotional infidelity. If partner related violence does not stop infidelity from happening the male mate will sometimes resort to suicide instead. The final resort to stopping infidelity inside of morbid jealousy is to commit partner murder. Women are much less likely to kill their partner, unless it is in self-defense. Morbid jealousy can occur in a number of conditions such as chronic alcoholism, addiction to substances other than alcohol i.e. morphine, cocaine, amphetamines. Organic brain disorders i.e. Parkinson's, Huntington's. Also with schizophrenia, neurosis, affective disturbances or personality disorders.
