I’m with you on this, I seethe and anger about the same things, I see and hear the same as you (only I probably seen more) I asked W to move out she either laughs or swears at me.
Anyway I’m practicing what people on here and people at home have told me, just leave her alone, Ignore here antics, get on with life, no matter how annoying, irritating or sick it gets.
We together can only do the best for us and our kids, fix ourselves up and maintain our sanity in readiness for the next phase of our lives.
