It's tough living under one roof in the midst of divorce. I don't know how you or anybody else do it.
Emotions are a powder keg. When things were bad with my oldest and I'd feel the anger of frustration welling up, I'd excuse myself saying I was getting emotional and would return to the topic when I was in a better frame of mind. When emotions start flying more and more comes out, kinda of like verbal diarrhea. I say, Imodium, please.
