It’s on reddit, which is basically a forum where you can create your own sub reddit. Like Justnomil, which talks about mother in laws and what shenanigans they are up to. Or AITA( am I the asshole), where people ask if they were wrong in certain situations. JustnoSo is a sub reddit forum about people telling stories about their significant other’s relationship issues and behavior. And they ask for advice how to deal with it. And I came across so many stories where the SO would act exactly like the seme in this story. Treating their partner like shit until they notice them drifting away, only to do something nice to reel them back in. Rinse and repeat. It talks about manipulation, control issues and gas lighting behavior.
So basically he's such an arrogant, selfish, narcissistic douchebag, that when he isn't- not even being nice really, just less bad- you feel like he actually did something nice for you and is worth sticking around for?! MAJOR red flag!!!
