Thanks for all the good advice, LH Steve Gigi, much appreciated! I ended up not saying anything at all.
Just came home after a few days with my parents and New Years with my brother. Apparently XW and D3 went and met OM today. I left the room as soon as I heard and later told W I don’t want to talk to her right now. I’m furious atm. Will go for a walk. Talk to her tonight.
