My Wife Wants Divorce Because I Bought "Only" Bread When Visiting Her Mum

I overheard my brother's friend explaining the cause of his quarrel with his wife, coz the wife has been fighting, raining curses and abusive words on the him since they returned from village on Sunday , saying her husband is wicked and all that. It happens like this. The husband returned from work on Wednesday and told the wife that mama is sick that by weekend they'll go and see her. The husband asked the wife to list things mama will be needing the wife outrightly said mama won't be needing anything, the following day been Thursday when he returned he still asked her mama will need some provisions and all that she said no that mama don't need sweet things they'll buy her bread on their way, the husband said what about foodstuffs, wrapper, shoe and bag? the wife said mama has them, the guy didn't say anything again, they set fr the journey on Friday, they got to a t junction where one route leads to husband village and another the wife village, the husband followed the one that leads to the wife's village and the
another the wife village, the husband followed the one that leads to the wife's village and the wife was like where are we going, the husband said ur village of course the wife asked please which of the mama is even sick he replied and said ur mum, immediately she got angry and started raising her voice in d car that why didn't the husband tell her that it's her mum that is sick, yelling that why will she go empty handed to visit her mother, that her mother needs clothes, provision and food stuffs so she told the husband they by to turn back to the nearest city to buy things fr her mother, the husband said never and he said so u think its my mother that is sick, that so its only his own mother that deserves bread abi, he stand his ground that it's only bread they're going to give his mother in law, they returned on Sunday and the wife has been making troubles that the husband disgraced her in her family and she won't forgive him that he really hurt her She stopped cooking fr him since they returned . The husband said if she doesn't stop this madness that he will divorce her. Now my take is what the husband did is it right or wrong. And women please our mother in law are also our mother.
