The relationship between my uncle and his wife is very bad, and they have a son

Their relationship is worsening by each day… if i try to tell you how bad their relashionship is, i dont have the words for it… they are baptised christians but from what i see, my uncle refuses any idea of jesus, he was exposed to a bomb when he was young, and one of his leg was cut, he have depression and gets angry very fast over the smallest of things… while the mother is more leaned to pray, but not so much, she doesent have a house management skill, part is due to her being lazy and part is due to her body not helping like feeling tired and stuff, which makes the man very irritated, and they get into a fight over smalledt things… now the man is making lots of things on purpouse to hurt the woman emotionally… the woman have needs which are not fullfilled by the man and same to the man… they do not talk to each others now, and the situation between them is very very bad… when the man is very very amgry he can hurt his wife, which happened before and the problem is when they get into a fight, no one tries to make the step to stop fighting, which actually escalate the situation a lot… they have one son of 6 to 7 years old…

Plz first i ask you to pray pray pray for them… like their problems is due to simple issues, there are no huge problems between them like adultery or something… and i know the way things are, they are going into the path of divorce…. im also afraid that the husband would hurt his wife before that… many uncertain things like what would happen to the wife after divorce, she doesent have anyone to help her out financially and soo many things…

Both are leaned to commit suicide especially the wife… and if they get into divorce there is a chance that things might not be fair for the wife…

Secondly, is there anything i may be able to do? I feeel so sad for them really, it didnt have to be this way, there was so many ways to avoid this….
