amy...good that yoiy told her that she hurt your feelings. I think it is good to be honest about your true feelings.
She sent you a "scathing reply".....I suggest that you just let that go...because you know that is her typical response, anyway.....the anger is her 'problem"....don't let it be yours.....
the anger will just eat you up.....
Maybe, take the dog for some more walks......lol.....
