I remember crying my heart out on the phone with you after I saw a picture of my ex’s new girl friend. Two year later, I found out that he was getting married. I feel normal. That is closure, dear! It took a long time. I could not have done that without you on my side all the time (even just to tell me that they are more meant to be).
So best friend, you can always tell me about your closures. I know sometimes it’s awkward. I know sometimes it’s painful. Many times it is simply impossible to let go the past. It’s normal. I will be there for you regardless. I will tell you how silly you are. We can laugh at our misfortune. Remember that it is their misfortune not to have us in their life.
