Parents divorce for many reasons. Usually divorce happens when couples feel they can no longer live together due to fighting and anger, or because the love they had when they married has changed. Divorce can also be because one parent falls in love with someone else, and sometimes it is due to a serious problem like drinking, abuse, or gambling. Sometimes nothing bad happens, but parents just decide to live apart.
Did you know it’s really common for teens to think that their parents' divorce is somehow their fault? Just try to remember that parents' decisions to split up are to do with issues between them, and not because of something you might have done or not done.
Some kids feel guilty about what happened, or wish they had prevented arguments by cooperating more within the family, doing better with their behavior, or getting better grades. But separation and divorce are a result of a couple's problems with each other, not with their kids. The decisions adults make about divorce are their own.
If your parents are divorcing, you may experience many feelings. Your emotions may change frequently, too. You may feel stressed out, angry, frustrated, or sad. You might feel protective of one parent or blame one for the situation. You may feel abandoned, afraid, worried, or guilty. You may also feel relieved, especially if there has been a lot of tension or fighting at home. These feelings are very typical and talking about them with a friend, family member, or trusted adult can really help.
