Dating is a fairly common thing with most Christian teens, and it takes a lot of courage to open up your heart to someone else. Yet opening up your heart also means it can be broken. A breakup isn't the end of the world, but that doesn't mean it's not painful.
Does that mean you just close yourself off to others? No. People will come in and out of your life, and the coming and goings aren't always pleasant. Then you have to deal with friends and family trying to be consoling or funny in order to help you get over your breakup. Often you end up feeling guilty that you're in pain.
Yet, you have to let yourself feel the pain so you can let go of the heartache. One of the best ways to do that is to pray. Have a conversation with God about how your are feeling. He's the best secret-keeper, anyhow. You can tell Him anything, and He's always there to listen. Allow Him to guide you through your heartache so you can heal. While everyone around you may give you advice of how to get over your heartache, it is God that will not only offer advice but actually help you heal.
