You need to listen to your DH and put a stop on all and any contact. If nothing else, she’ll have had the last word, but have no idea of whether she’s hurt you, and she’ll have just gone from 2 possible loving Grans……to none. Just what she deserves, because she’s not a child, but a nasty, poisoned woman who clearly likes to live in the past and think she’ll always have the chance to strike a blow for her equally stupid Mother!
Ignore it, Axzder.You behaved well, she’s beyond hope. Save your love and concern for those who deserve it - and forget what she said. It’s the voice of a spiteful loser and you must believe you’re worth so much more. End the game and move on.💐
