Now that I'm staying calm and following the rules, I find that she is looking to pick fights over things. I don't take the bait and she calms down fairly quickly and apologizes.
Another thing that I found out today, who knows if it's true though. She had told me that the AP told his girlfriend what happened and told her to move out. Through someone who knows someone who knows him, she caught him and moved out on her own. Not that it really makes adifference, but it's nice to know that he's lying to her already. Unless she knows but wouldn't tell me.
