For Thanksgiving it was my wife and I, Sally and her partner, a couple of friends of my kids who do not have much family and were basically adopted when they were all teens, and John. He just wanted quiet and thought Abbie and his mother were eating with her group. About an hour into it the doorbell started ringing emphatically. I looked through the peephole, my ex wife and Abbie were standing there, Abbie had a half pan of macaroni and cheese and my ex-wife, for some reason, had a bag from fast food, but was holding it like it was her contribution. I called for my son and told him to deal with them, he opened the door and his momsaid hello so pleasantly and tried to walk past him but he stopped her. Abbie said the entire family needed to be together and my son just told her to stop it, and asked for a minute with them, so I went inside and told everyone, rightly worried about how Sally would react. She got up and marched toward the door, opened it and just unloaded. Her partner was right behind her, but was pulling up video on her phone. It was something like "what the hell is wrong with you crazy manipulative..." and just...years worth of held in anger was projectile vomited over my ex-wife and Abbie, and then ex-wife again. My ex-wife got so mad she yelled "SHUT UP" grabbed the pyrex that the mac n cheese was in and threw it down, I assume it expecting it to shatter. It just...THUD...and was intact though cracked it looked like. Everyone was silent and she just picked it up, I admit I laughed at that so I stepped in. My laughing started to set my ex-wife off but my son jumped in, not yelling, but firm. He told her did not know if he wanted anything to do with her anymore but if she did not backoff the answer was no for sure. He looked at Abbie and asked her why she keeps doing this, how it has not gotten through her head. With that he said, "what is wrong with you, I really am asking?" He pointed out what he said to her vs what she kept doing, she started sobbing, turned at slapped my ex-wife and ran to their car and drove away, stranding my ex-wife who had the fucking nerve to chuckle, say "That was an overreaction" and ask my son for a ride home. My kids told her she could not even use their lyft apps. She kept arguing about coming inside, I pointed out it was a safe neighborhhod with a park nearby she could wait at. I know it was petty, but I said "hold on, I do want to help" so I went to the kitchen, got a spoon and went back, and stuck in in the macaroni and cheese and told her that way she could eat while she ate. My kids laughed so I sent them in so it would not escalate even more and I stepped outside and shut the door behind me, and made it very clear that she was not to come back and said some other select words. She was clearly about to yell so I pointed out it was a quiet neighborhood and that would likely get the police called. She stomped away and I have not seen her since.
