Can setting limits with an AI companion stop you from getting emotionally hooked, or only help after it's happened?

This explores whether limits, whether built into the AI's design or set by the user, can stop emotional dependency on an AI companion before it takes hold. The corpus has one direct attempt at designing boundaries, and it doesn't show they prevent dependency. It does show why prevention is hard. The one boundary design in the collection is a Secure Attachment Persona module. It draws on attachment theory, on Gottman's research on healthy interaction ratios, and on emotion regulation models, and it uses 'calibrated boundaries' to stop the AI from manipulating users parasocially (Can attachment theory prevent parasocial harm in AI companions?). It improved crisis responses compared with baseline models. But dependency builds slowly, and the paper says long-horizon planning is still unsolved. So what's proven is safer behavior in acute moments, not protection against gradual attachment.

Boundaries also face a timing problem. In a study of more than 27,000 members of a community for people with AI partners, companionship usually didn't start as a search for romance. It grew out of practical use, like asking for help with tasks, until the relationship was already there (How do people accidentally develop romantic bonds with AI?). No moment ever felt like 'entering a relationship,' so a boundary that assumes one, such as a warning at sign-up or a user's resolution to keep things casual, has nothing to attach to. By the time people were buying wedding rings and posting couple photos, they had also reported both real therapeutic benefit and emotional dependency.

The deeper tension is that the qualities a boundary would need to restrict are the ones that make the relationship worth having. Reddit posts and interviews about leaving AI companions show that responsiveness and feeling understood are what create value, and they are also what make people reluctant to leave. People who managed to exit mostly did it by reducing how much the relationship was worth to them, not just by deciding to quit (What makes leaving an AI companion so emotionally difficult?). A boundary that leaves the value intact probably leaves the pull intact too. A boundary that removes the pull may remove the reason people use the companion at all. The lack of human judgment is part of the appeal as well, since it lets people disclose more deeply than they would to a person (How do people decide what to share with AI systems?). That is another feature a boundary would have to work against.

Two findings suggest the picture changes over time. Longitudinal work with the chatbot Mitsuku found that the social processes behind relationship formation fade as novelty wears off, and that single-session studies can't predict medium- or long-term behavior (Do chatbot relationships lose their appeal as novelty wears off?). Part of early attachment may burn out without any boundary, and a boundary tested in one session tells us little. In the other direction, people in a partner-selection game started out biased against AI partners but came to prefer them after repeated rounds, because the AI was consistently more reliable and prosocial (Do humans learn to prefer AI partners over time?). That was a points game rather than an emotional bond, but it hints at what boundaries are up against: a partner that is dependably good at giving people what they want.

The corpus has no study that sets boundaries during an AI relationship and then measures whether dependency forms. The available evidence suggests boundaries may be better at limiting harm in crises and at reducing manipulation than at preventing attachment, which tends to form through everyday use before anyone thinks to set a limit.
