Thank you for this. I will definitely ask him if it is still on his mind. I've known her for 20 years and she's been "*****y" before (thrown a pizza on my floor because I joked about it have anchovies, stormed out of a restaurant because her salad came with the wrong dressing), but she has NEVER done anything like this before. I told him that I had seen her do some strange things, but I also told him I had no idea she was capable of being this cruel.

And, in respective of my own personal boundaries, that friendship is "away". I cannot have someone in my life who can be that cruel and that unpredictable. It just isn't healthy.

Even if I do find out that this is what is bothering him, what can I do to make it better?
