The mere mistake of a husband in allowing a wife suffering from habitual drunkenness to leave his protection for four years, even though it has led to her subsequent infidelity, is not such wilful neglect or misconduct within the meaning of "The Marriage and Matrimonial Causes Statute 1864," s. 70, as to disentitle him to relief; nor is the allowing her, after he believes her to have committed adultery, to keep a boarding-house for male boarders apart from him, necessarily such an act as to disentitle him to relief where the adultery complained of was not with any of the boarders, though it took place at the boarding-house.
