Will I ever heal completely?

All throughout my high school years (I’m a senior now) this this boy and I have been on and off fooling around. He really messed with my feelings and broke my heart repeatedly. Now, I have a healthy relationship with my boyfriend who treats me perfectly. I love him with all my heart.

Well my youth group are on a youth ski trip and the guy who broke my heart and those old wounds on my heart have opened up and it’s making me sad just seeing him and being in the same cabin as him.

Do any of you have any advice that will help me stop thinking about the past?
