I think your DH was more than generous to her to maintain a rel
ationship with her after she treated you the way she did. I'm a little baffled, really, as to why he didn't maintain a united front with you, unless he made it very clear to her that he wouldn't tolerate her treating you that way any further and that his staying in contact with her didn't mean that he accepted that behavior.
That said, I'm absolutely on the side of not making any contact with her about the petulant/passive pie-package posting.
