There was a time during the day, when the venting was repeating itself. I excused myself, and took the dog for a walk.
This is good. Do you tell her WHY when you do this? Make sure you do. Say something like "I'm sorry, but I don't need to be b*tched at. If you're going to talk to me so disrespectfully, I'm just going to take the dog for a walk." And then do so.
