There is a difference between saying goodbye & letting go. Goodbye is not permanent. You can meet years later & share what happened in your life. You can smile & laugh about all the nonsense that you both went through. However, letting go is being okay with never seeing this person ever again, being okay with never knowing how their life turned out, being okay with fifty or more years of silence, being okay with running into that person at a grocery store & having them not acknowledge your presence. This is the part of life that doesn’t sit well with me and never will. It tears my heart in pieces, robs me of gratitude, drains me of anything positive & eats at the faith that holds on.
