I'm a guy and I lived with a Polissa a long time ago. She knew full well that I would never lay a finger on her (and that even if she was wrong about that and I actually did, my life would be ruined and/or she could blackmail me about it), and so she knew she could push my buttons all day every day without any consequence. Why some women do that I don't know, I think it's BPD and a desire for the drama it creates, but in the end it's just emotional and psychological domestic abuse. And yeah, I knew it was time to get the fuck out when I found myself seriously wondering about the logistics of disposing of a body because it seemed the only way to get her permanently out of my life. In the end the breakup was as horrific as you would expect breaking up with an abusive BPD psycho to be, but I learned a lot about emotional resilience from the experience.
Joh is a retard for popping her, but he's a known angry retard and that's not a surprise. I bet Polissa is delighted that Joh hit her, she can hold that against him forever. I can imagine what an existence with a self-centred narcissist like Polissa must be like. People like that (men and women) have ways of psychologically trapping you in hellish relationships with them. The main two methods are firstly to destroy your self-esteem and self-confidence by constant criticism and nagging, and the occasional explosive outburst of rage, and secondly to make you dependent on them. This is most apparent in Poh and Joh's relationship when the two of them describe driving together. Poh is a chronic back-seat driver, a situation made worse by the way Joh reacts to criticism by doubling down on whatever stupid thing he did just to show 'em (a trait he shares with other egotistical retards like Cobes or Pat Tomlinson), giving her even more reason to bitch at him. But at the same time, he's said that he thinks it's Poh's responsibility to teach him to drive. She has manipulated him into thinking she's the only one who can help him. Also remember that she makes phone calls for him because he's too much of a retard to make them - but also it means that he feels he needs her in order to be functional. Her continued picking away at his self-esteem means that he probably believes that he can't do better than Poh, whereas even in his current state he probably can, especially if he calms the fuck down (which getting away from Poh would assist with to no end).
I've repeatedly called Poh a human barnacle - she will glue herself to someone and provide nothing for them, while leeching resources from them and the environment. People like Poh are black holes. No matter how much you give them they never give anything back. They're always asking for handouts to "just get back on my feet" and then just stay attached to their victims indefinitely. The only solution to dealing with them is to just walk away, otherwise they will ruin your life and that of your family, by draining time, money and emotional energy that should be going into people who will reciprocate. What destroyed Joh's relationship with his family? Poh did, by moving him into the Tub Trailer and making him fix it up, which in turn made him demand help from his family over and over which eventually became so aggressive they cut him off entirely. The most skilled abusers don't just isolate you from friends and family - they manipulate you into doing it yourself, and that's what Poh has done to Joh. She knows he's angry and stupid, so she knows that she pushes him into situations where he will tard out at his support network he will lose it and become completely dependent on her for everything, so she can drain him into the kind of husk he is now.
Joh is too stupid to see that Polissa is doing this to him. I don't know what his relationship history was before he met her, but if he was inexperienced (like I was when I was with my own Polissa) he won't know to recognise any red flags. I think Joh will stay for a long time. Him trying to beg forgiveness from Poh rather than taking the opportunity to run for the hills may turn out to be the biggest mistake of his life. This will be the pattern from now on, she will make his life hell, he will snap and do something stupid, and she will make him prostrate himself and tighten the ratchet. He'll never spot the pattern.
I'd feel sorry for him if he wasn't such a cunt.
