That's very true. Recently I had a minor dispute (I didn't know until later that was a dispute, because I didn't think much of it at that time) with a close friend and she switched to a very formal way of communication. She is not ready to address the issue, but her interaction changed from friendliness to formality. I don't like it and couldn't resolve the problem even after trying. So I decided it's time to stop trying to fi the issue when the other party is playing hard to get. I made peace with the whole thing, although at times I feel wronged. Time to learn letting go.
