ES:
Maybe you have outgrown this friend? I am sorry, I know you were trying very hard to be kind to her, not to upset her....
But perhaps this is a good thing. Your green light to move on.
I think most of us who are healthy people do understand. For most of us, when a beloved friend comes to our town-- or we go to theirs-- we are happy even just meeting up for coffee or lunch and catching up for the couple of hours they might have available. We are glad that they were able to make the time to see us.
I'm sorry your friend couldn't be gracious and understand that some things aren't about her. She made assumptions, ignoring your previous information and hesitations. Perhaps she just thought you would be a pushover and you pushed back? Perhaps she's changed for the worse since you used to spend time with her?
When you feel better, I do hope you find a time when you consider this a very hard blessing to receive. Either she'll get her act together and apologize (and do it before she decides she wants to stay with you again) or she'll just disappear. You really did the best you could, and again-- most reasonable people would have no problem with what you had offered.
Hugs. Sorry this sucks. I hope you do something nice for yourself tomorrow.:)
