Should she endure or leave him

Its been 22 years of suffering since she decided to get married to him they constantly fought and there was never a moment of peace she should have listened when her mother told her to leave him after she gave birth to their first child but she thought he would change now she knew that a leopard could never change its spot now her mother was dead and all her relatives have left her to her fate she was all alone with no where to go and four children to care for

What was a mothers gain in life to look after her children and see them become important people in life,but she was stranded had no money and her so called husband after giving him every thing that she owned has beaten,insulted,abused,cursed and reduced her to an empty shell of a person i should go but i have to think of my children who will take care of the two little ones left i have to endure and see them through.......
