Was it a good idea to write a letter about what they did that upset you? Not accusations just to explain without being mean? Or was it better to just break up and say i dont want to see you anymore and that's it? I'm talking about a one year v close friendship.
Its always better to give your reasons. Its better for you because it gives you a chancd to reflect on your decision and have more confidence in it, and its better for them so they can learn from what happened by understanding your side of it.
