Should we wait till it all results in bullying before we make corrections in our marriage?

My female friend told me how her friend was brutally abused in her marriage.

This has been a repeated action until one day that the man beat the woman till she fainted.

He left her for work. Around 6pm, she woke up and rushed to prepare herself for work. Only to have found out that it was late already.

She checked her phone and had gotten several missed calls even from their children's school. She ran to pick the children and call her place of work just to lie.

Guess who she is?

A barrister!

The man came back but didn't even show any remorse. The woman was ironing her children‘s school uniform and she suddenly had the thought, so, if I die, that is the end.

She went to where her husband was sitting and pressed the hot iron on his cheek and hand. She ran to her friend.

She only returned the following day and since then, the marriage takes the good shapes it is supposed to take.

Then, I ask, why do we choose violence in our marriage
