Most of the time this is the best way to go. You learned that just like I did. It means nothing to be “right”. Not when the situation does not change, improve, or growth is witnessed. Let it go. You can’t win 99% of the time so why waste your energy?
And why did it take us so long to realize it?
I’m sorry you had this sadness. I wonder what your friend was upset about. Was she ever really your friend?
