After a dinner party, your partner was openly affectionate—touching your arm, laughing at your stories, pulling you into conversations. On the drive home, something shifted. By the time you were inside, they were quiet, answering in short sentences, moving through the apartment alone. The private interpretation arrives fast: they were performing earlier, they are already tired of you, the warmth was social habit rather than real feeling. Your chest tightens. You either move toward them for reassurance or go cold yourself before they can. Neither response addresses what actually happened, and your partner is left confused by the person they were just celebrating an hour ago.
