It's very common for teens to believe that somehow they have caused their parents to split up. You may be asking yourself things like, "Was it something I did?", or "Is it my fault?". Or thinking, "It wouldn't have happened if I hadn't argued so much, or I had done better at school, or..."
If you are saying things like this to yourself, stop! It's not your fault.
Remember: Parents split up because of problems in their relationship. You are not the reason why they are separating.
You are not the reason for your parents splitting up. Parents split up because of problems in their relationship.
In the vast majority of cases, children get to spend time with both parents. How much time you spend with each parent, and exactly how that will work, depends on your custody and access arrangements.

Parents usually try very hard to solve their problems before they take action. If you're not sure what your parents' reasons are for splitting up, you can always ask.
