Crazy Drunk Lady Next Door

Our neighbor divorced is wife not long after moving in and a few years later found a bar fly to bring home. She has never left. She is usually drunk and angry at him for anything and everything. He has been in serious trouble with her for: someone taking her parking space, not cooking what she wanted for dinner, and not calling her enough when he travels for work. It has always been off and on but the past couple months she is at the house all the time, rarely leaves, and is either drunk or fighting with him all the time. And he leaves once she gets going. So she calls him on the phone and chews him out from the backyard for some reason instead. He almost divorced her at one point, but must have missed the abuse?
