Everything from witchcraft to the assessment of the women's attitude and the manner in which she spoke to her husband. And, of course, the possibility that he feels emasculated by her constantly challenging his authority.
His infidelity is only natural as a man. The physical abuse was probably provoked by her. His alcoholism is his only way of escaping a cold home.
And she could not possibly mean that she would leave her husband, deprive her children of their father, sour relations between the two families and bear the indignity of a divorce just because her husband made a few mistakes.
I remember the day she wore her long skirt and tied her doek tight around her head as if to restrain all reasoning and common sense, and tainting the conversation by the men delegated to negotiate her return.
The less she said, the better her position and the more humble and submissive she appeared.
She sat with her head bowed down and only answered when spoken to. She had to apologise for making their home hostile. She promised to serve him better and be a better wife.
She remains married and respectable, and occasionally nurses a bruise.
I do admire the tenacity and fighting spirit displayed by Moyo. But the same cannot be said of wives.
But I know for sure that, had a few more women accepted that their marriages had broken down; had a few more walked away from where they were no longer wanted; and had a few spoken publicly about the challenges they prayed silently about, a few of them would be alive today.
