Oh my gosh I’m so sorry for everything that you went through.Having been the victim of emotional and verbal abuse the scenario is pretty clear and familiar. Same trajectory as Gaby Petito.
Emotional abusers are relentless and push the same buttons over and over you are trapped in circular arguments riddled with targeted cruel comments mined from information shared when the relationship was new and happy. For instance I have a terrible mother my ex ended every argument with “you are just like your mother”. If you try to escape an argument they scream that you are a crybaby that runs or that you can’t have an intelligent conversation and they sneer and laugh at your emotional anguish. I never slapped (reactive abuse) like Gaby and the head teacher but I can imagine it. He likely worked her into an emotional frenzy and claim she was the abuser before threatening her by calling the cops (likely saying she’d lose her daughter haha). My ex would rage inches from my face so I could feel the spit and taunt me to “hit him”. I never did but I self harmed twice to get him to stop. I picked up a metal bar and hit myself in the forehead splitting the skin; he laughed and said keep doing it. So I understand the slap.
The dinner party was probably a trigger. She likely couldn’t be persuaded not to take this job and he was resentful. Then something at dinner embarrassed him. This type is vengeful.,
Example my ex would be delightful at parties but I was always afraid to get in the car when leaving. Id have a great time and as soon as the doors closed, “why the *uck is the gas tank at a quarter filled!! This car needs to be at half always!!!” Or “why at dinner did you keep saying “my house” vs “our house” are you trying to rub it in that you bought the house to everyone!!!”. Etc etc. so I’d be screamed at all the way home from every party. They listen closely for perceived slights and are infuriated if you take a stand on anything or embarrass them (like Gaby P did getting him in trouble with the police- he’d never think it was his fault.
Abusers POV: You made me mad! And now look what happed to me!!!
Sad
I feel this so hard because I experienced this too and fully believe that Emma did too.
I’m so glad you are out and hope you are okish now. <3
