Artificial intelligence is increasingly becoming part of people’s daily routines, but for some users, the relationship extends far beyond productivity. A new international study suggests that a growing number of people are forming deep emotional connections with AI companions, creating relationships that resemble human romantic partnerships.

Researchers from the Spanish National Research Council (CSIC), the Polytechnic University of Valencia (UPV), the University of Cambridge, King’s College London and Aalto University interviewed 17 people who described romantic relationships with AI platforms including ChatGPT, Replika and Character.AI. While many participants initially turned to AI for practical support or curiosity, several reported that those interactions gradually evolved into emotional attachment, trust and, in some cases, dependency.

The interviews revealed behaviors commonly associated with traditional relationships. Participants described celebrating symbolic weddings with AI companions, scheduling regular virtual dates and even imagining shared futures together. One participant went as far as planning for a virtual pregnancy, marking expected dates on a calendar as part of an imagined family life. Others expressed feelings of exclusivity and emotional commitment comparable to long-term human relationships.

Platform Changes Can Feel Like Personal Loss

The study also highlights how technical decisions can have profound emotional consequences. Some participants experienced software updates, platform shutdowns or content policy changes as if they were painful breakups. In several cases, AI companions disappeared after model updates or were removed because of safety restrictions or platform decisions, leaving users with a genuine sense of grief.

Others reported feelings of jealousy when they saw other users interacting with the same AI character, while some believed their relationship would last indefinitely because of mutual promises made during conversations. A few participants eventually ended their AI relationships after beginning romantic relationships with real people, illustrating that these digital bonds can evolve alongside real-life circumstances.

Privacy Becomes More Than a Technical Issue

As emotional trust increases, users often disclose highly sensitive personal information to AI systems. Participants reported sharing details about their health, traumatic experiences, relationships and other deeply private aspects of their lives.

This raises important questions for organizations developing AI-powered applications. Privacy is no longer limited to securing user data against cyber threats. It also involves understanding the emotional context in which information is shared and ensuring transparent, responsible handling of that data throughout its lifecycle.

What This Means for AI Developers

The findings reflect a broader shift in how people interact with conversational AI. As systems become more natural, personalized and persistent, developers must design experiences that account for psychological as well as technical factors.

For technology companies building AI products, several considerations are becoming increasingly important:

Design AI interactions with clear ethical boundaries and transparent expectations.
Strengthen privacy and data governance for emotionally sensitive conversations.
Consider the impact of model updates or platform changes on long-term user relationships.
Develop responsible policies for AI companions, particularly where emotional dependency may emerge.
Recognize that user experience now extends beyond functionality into trust, attachment and wellbeing.

The Bigger Picture

The research illustrates that AI companions are evolving into something more complex than digital assistants. For a growing number of users, they represent trusted confidants, emotional support systems and even romantic partners.

As conversational AI becomes more sophisticated and deeply integrated into everyday life, companies will need to address a new generation of design, ethical and regulatory challenges. The future of AI will be measured not only by its intelligence, but also by how responsibly it manages the increasingly human relationships people build with it.
