I think it would be really helpful to identify 'Retroactive Jealousy' or 'obsession with partners past sexual/romantic relationships' as a sub-category of OCD. There is a fair bit online about this and many people who describe their struggles with it (while otherwise not being jealous people)… yet I've not seen anything on any OCD websites about it, or even acknowledging it. Anything that can be done to bring awareness, support or confirmation to this distressing illness would be amazing!ThanksRob
I would just use every time you're triggered in daily life as an opportunity to use the four steps. The steps involve refocusing your thoughts rather than responding with the compulsions you listed above.
