§ 2a:34-2.

Divorce from the bond of matrimony may be adjudged for the following causes heretofore

established by satisfactory proof that the parties have ceased to cohabit as man and

wife; c. Extreme cruelty , which is defined as including any physical or mental cruelty which endangers the

safety or health of the plaintiff or makes it improper or unreasonable to expect the

plaintiff to continue to cohabit with the defendant; provided that no complaint for

divorce shall be filed until after 3 months from the date of the last act of cruelty

complained of in the complaint, but this provision shall not be held to apply to any

counterclaim; d. Separation, provided that the husband and wife have lived separate and apart in

provided that where the action is not commenced until after the defendant's release,

the parties have not resumed cohabitation following such imprisonment; h. Deviant sexual conduct voluntarily performed by the defendant without the consent

of the plaintiff ; i. Irreconcilable differences which have caused the breakdown of the marriage for
