My mother in law is a terrible, abusive, manipulative individual. She uses virtually everybody around her in sick head games of deception. First off, she emotionally abused my wife growing up (who also has ASD) and tried her very hardest to make her feel like she was destined to fail and be her inferior, and consistently put her down her entire life, beat her and then beat her some more when she flinched, and when she got older this scum had the audacity to claim my wife was "faking" her autism and was actually just a brat.
It isn't just limited to my wife. I never hear this women say a nice thing about ANYBODY so long as they're not in the room to hear how she truly feels. She basically slyly puts down and demeans and belittles everybody when they aren't in the room. Whoever is with her in the room, that's her pal. Whoever isn't, they get to be talked badly about by her. She made a specific effort to make me feel like my wife was an incompetent loser that wasn't going anywhere in life, meanwhile trying to convince my wife I was a selfish ass who doesn't care about her and it worked and we fought until we figured out she played us. She treats my wife's dad like absolute garbage, unless she wants to use him to get involved in her disagreements because the man's good nature makes him want to defend his wife. But she also consistently reminds him how little she loves him.
She told my wife she did well in her driving lesson and told me she did terrible behind her back. My wife once won a competition in her childhood and her mom tried to gaslight her and tell her she never won it she just told her she did when apparently, my wife was told she won by the school not her mom so basically her mom was trying to deny her of feeling like she was good at something. And pretty much anything my wife has aspirations in, she'll make sure to tell me when she isn't around how much she thinks she'll fail. She also regularly insults my wife's appearance and can't take any criticism without yelling.
The worst part is I'm currently on a visit at this garbage human's house. I tried my very hardest to follow her house rules when visiting it as a guest and yet she still consistently s**ts on me when I'm not in the room or passive aggressively. I've tried my best to be nice but I just f*****g hate this women and I don't think I'm going to be able to hold back this massive urge to completely explode on them and tell them exactly what I think of them. What should I do?
