Heavy. I don't think u did anything wrong. Sounds like you kept your cool and made it about the kids. The ww is impossible for me to understand. My ww tends to find anger and indifference to be her go tos. If she's mad at me, it makes it easier for her to justify we she's doin what she is. Maybe yours was mad or annoyed because you have her no reason to be and she's grasping.
Who knows? You can control you and it sounds like you did a great job in a difficult situation
