Turns out he started taking a video of me completely livid telling him to leave while of course he's perfectly calm through the whole vid. Saying I hit him multiple times which is why he threw shit which has NEVER happened in 3 years. When I wouldn't leave him alone because I wanted him to get out, he sent the video to my sister.

I know someone who's in a toxic marriage with a shit bag. When they get into fights, one records conversations and saves texts to show the other as mentally unstable, making sure to not have anything that incriminates themself in the file, though both are being equal assholes to each other. When the fights lead to talks of divorce, they say they'll use it in divorce proceedings to show the other is unstable. Then they make up, until the next fight. He is a master manipulator and user.

You need to protect yourself because any natural reaction you have to this situation can and will be manipulated to make you look like the aggressor and they the victim. And they will succeed because they had the forethought to collect evidence along the way while you were naive and thought they viewed you as a partner, not someone they needed ammunition against. Also, this relationship is over.
