NO!!!!. She didn't change or she wouldn't be friendly to anyone. She reacted to your poor behavior. What you are experienxing is tbe negative consequence that your pior behavior caused....that is not her changing. It was a forced reaction & behavior like that would cause anyone to stay away for fear if they were tp be friendly in any way it would encourage your bad behavior all over again...when people are treated the way you treated your supervisor their only choice is to set boundaries & keep a complete distance.

You still need to STOP blaming her for the situation YOU CAUSED.
