His Wife Beats His Mother – Please Help

It was a very painful and terrible tale from a pal of mine this morning as he was telling me the dramatic scenes taking place in his house he was in a very confused state as he lamented how his wife fought with his mother ( but from my view beat his mother) I was actually shock and furious but couldn’t find any reasonable advice coming out from my brains….

I couldn’t imagine my mother being touched by my wife (not married yet) it was very heart touching…..
the guy is confuse cause he love his mother and he wife so much he just don’t know what to do
his mother would be staying for at least a month b4 leaving and the tension in his house is like that of a woman in labour…..

what would you advice him to do…..
