Many teens really believe that their parents will get back together. They try very hard to make it happen by being on their best behaviour.
Sometimes this is a way of denying what is really happening, in order to protect yourself from the painful reality.
Chances are, your parents reached this point only after trying very hard to save their relationship, and their decision to split up is final.
It's hard, but it's probably better for you to begin to accept the situation as it really is, and get used to the changes that you are facing, in order to get on with your life.
Lots of teens worry about breaking the news to their friends. But separation and divorce are very common these days.
Good friends will be glad you've told them. You're still you, even though your family is changing.
If there are things you need to know, ask. You have a right to ask questions about what is going to happen and why.
Many teens whose parents split up feel anxious about their own relationships in the future. But just because your parents split up doesn't mean the same thing will happen to you. What happens in your relationships will be up to you, not your parents!
