wow, what a response from them. I, personally, would drop them both. It's hard losing friends, but these women clearly are not the kind of friends that you need.
I agree with Mike, a lot of my old friends (during time with AH) I no longer really communicate with. I have found new (BETTER!) friends who appreciate me for me.
The sting is still there from the loss of some of them, but I am much happier. I think your friends in this case are the ones with the problem.
I wouldn't engage any more with them.
