Yeah I developed a cuck fetish after being cheated on. Its a defense mechanism, your brain fetishizes the trauma so the weight of what happened doesn't destroy your ego. Its just coping with the horrible thing that happened. Similar to what happened when rape or violence victims fetishize violent sex and rape.
I dont know how to cure it, I dont know if there even is a cure. What I do is just ignore the feelings and not act on it. What I really wanted though was to have an open relationship with a slut that would cuck me all the time. I can jerk off just imagining being married and my wife showing me videos of guys way bigger than me fucking her and making her scream in a way that I cant. I also fantasize about getting back with one of my exes and having an open relationship, taking her to well endowed escorts so I could watch her getting fucked, I even have a favorite porn actress that looks like her and I watch her videos fantasizing I'm watching my ex being fucked. Matter of fact I usually masturbate watching videos of girls that looks like my exes and imagining its them and I'm being cucked. Basically I'm fucked in the head.
