To help with understanding why parents might split and why it is not related to dislike of the children involved
The first thing to remember is that you are not alone. Thousands of children experience the stress of parents separating and divorcing each year. How kids feel about a parent moving out (or parents just not being together anymore) often depends on age, personality, and the circumstances of the separation and divorce process. Every divorce will affect the children involved — and many times the initial reaction is one of shock, sadness, frustration, anger, or worry.
But children also can come out of it better able to cope with stress, and will become more flexible, tolerant young adults.
