If a break-up is messy or protracted, this goodbye letter to an ex can provide a clean break for both parties.
This is difficult for me and I'm not sure why. We already broke up, which was a terrible exercise in heartbreak and loneliness for me. I think that loneliness is the reason it was so easy to get caught back up in seeing you, talking to you, and feeling safe with you again.
I need a clean break this time, which is why I'm writing this in a letter. I know that if we continue to see each other this often, something will happen, and it will only be harder to disentangle ourselves from this mess. Since we've already decided not to be together, I don't think that we should continue down this path.
It's hard to say goodbye, but this needs to be the last time. It hurts too much to do this again.
