Depends on what age. Younger kids tend to think it's their fault somehow. It also depends on the situation. I'm glad my parents are splitting up, it's been awful with them together most of the time. But sometimes the child thinks it's horrible, and that it's not right and that the parents need to be together.
Well this happen to me when I was 4 and for years I always thought It was my fault well I soon told my parents that I thought It was my fault and they told me why they got divorced and I soon learn it wasnt my fault
Most kids think that's the end of their life. They think they will have no more parents since they don't know on which side to follow. This brings stress leading them to thoughts of taking away their lives or run away home.
