I'm sorry that your friend has treated you the way she has. This seems to have been going on for a while with some subtle signs.

I must say, I don't believe it was fair of her at all to not communicate with you regarding the agreement she had made with your cats. I can't really speculate what her intentions were as she does not appear to have communicated this to you either. Either way, that's a real let down.

I'm sorry your thanksgiving turned out the way it did. You were in a very difficult place. But family do forgive us.

There is no sense to be made of this senseless situation your friend has put you in and you may never know the answer.

Unless she initiates reaching out to you first next ... Then I'm not sure where the rest of your friendship would be heading.
