Built by someone who couldn’t stop dwelling.

Then found the science that explained why.
Retroactive jealousy is the obsessive focus on your partner's sexual and romantic past. It manifests as intrusive thoughts, compulsive questioning, research spirals into your partner's history, and vivid mental imagery of past scenarios.

Rather than treating this as a character flaw or relationship red flag, we treat it as a treatable pattern. This 12-week science-backed protocol teaches you how your attachment style fuels retroactive jealousy, how to interrupt the obsessive thought loop, and how to rebuild genuine security and trust with your partner.
I went deep into the research — behavioral neuroscience, behavioral science, dopamine systems, habit formation. Newport, Harris, Alter, Eyal. Thousands of pages. Hundreds of experiments on my own relationship with technology.
Over about six months, I went from compulsive checking and constant distraction to genuinely understanding my patterns and building around them. Not by trying harder — by trying differently.
Each week, you'll learn the neuroscience of why these thoughts feel so real and so important, you'll identify your specific triggers and obsessive patterns, and you'll practice concrete techniques to interrupt the mental movie-making before it spirals.
If retroactive jealousy is running your relationship, this 12-week protocol will teach you how to interrupt the obsessive thought loop, rebuild trust, and reclaim intimacy.

The rescue kit gives you five emergency techniques you can use the moment retroactive jealousy spirals—when the mental images are vivid, when the urge to question your partner is overwhelming, when you're stalking their exes online.
Unlike traditional couples therapy that focuses on relationship communication, this protocol directly targets the neurobiology of obsessive thought patterns that fuel retroactive jealousy. We show you how to metabolize the difficult truth about your partner's past without letting it contaminate your present.
