Everyday shorthand you will see
"Discovery" or "D-day" refers to the moment infidelity came to light. "No-contact" describes an agreement to end all communication with the other person involved. "Trickle truth" describes new details emerging gradually rather than all at once, which is common and often unintentional.
How members describe roles in a conversation
Members generally write "the betrayed partner" and "the partner who was unfaithful" rather than loaded labels. Using plain, specific language rather than shorthand initials helps new members follow a discussion without needing a glossary.
