Is AI Becoming the Third Person in Your Relationship?
People can now use AI to rehearse arguments and seek comfort—raising a new question for couples.
An AI that hears only your side may reinforce your interpretation of the story.
Preparing for a hard conversation can strengthen intimacy; outsourcing the conversation can replace it.
The argument ends the way arguments often do now: two people in separate rooms, holding separate phones.
One opens a chatbot and types out the fight. The calm, understanding reply arrives in seconds. For a moment, the machine seems more understanding than the human in the next room.
No one has yet measured how often this scene occurs; the research is young. But as people use chatbots to interpret arguments, draft difficult texts, and seek comfort at 2 a.m., a new question is emerging: When does AI help partners communicate—and when does it replace communication? AI can prepare us for human intimacy—or protect us from having to risk it.
The Case for the Rehearsal Room
Let's be fair to the machine first. Difficult conversations often deteriorate for familiar reasons: people enter them emotionally activated, uncertain what they actually need, and more prepared to accuse than to request. Talking it through first—with a friend, a therapist, a diary, or an AI—can lower the temperature and turn "you always" into "I felt." Used this way, the chatbot is a rehearsal room: a place to get confused thoughts into order so the conversation with the partner can happen better. The clarity comes home.
Intimacy grows when vulnerable disclosure is met with understanding and care (Reis & Shaver, 1988). AI can support that process when it helps someone communicate more clearly.
The Sycophancy Problem
But there is a structural concern with a name: sycophancy. Language models can adapt their responses to agree with users' expressed views—even inaccurate ones (Sharma et al., 2024). Those experiments examined question-answering, not couples counseling; applying........
