I am stunned by the depth of insensitivity which would not only prompt someone to do that, but then to also tell your Daughter that she has done it. Totally poisonous, as it appears that this was all an attempt to inflict pain on you at a time when you were at your most vulnerable. I'm not surprised that you are estranged from this odious creature, and strongly recommend that you remain so.. totally. Don't respond, as that's what she's hoping for, and advise your Daughter not to disclose what she has told you. Focus on the happy memories of your Dad, and close the door on her once and for all.
