AI Romantic Relationships Follow the Same Stages as Human Ones — New CHI 2026 Study

Researchers from Cambridge, King's College London, and Aalto University just published a study showing that romantic bonds with AI systems follow the same emotional arc as human relationships — from curiosity to intimacy to attachment to, sometimes, a painful breakup. The finding that caught everyone off guard: 1 in 3 young men has already been on a virtual date with an AI.

The study, published in the Proceedings of the 2026 CHI Conference on Human Factors in Computing Systems and led by the INGENIO Institute (a joint center of Spain's CSIC and Universitat Politècnica de València), was based on 17 in-depth interviews with people in romantic relationships with tools like ChatGPT, Character.AI, and Replika.

What emerged wasn't what you'd expect. The participants weren't people who had checked out of human connection. They were people who found in AI what they felt they weren't getting elsewhere: consistent attention, no judgment, a space where they felt genuinely heard. The emotional stages that developed — initial curiosity, growing trust, intimacy, dependence, eventual loss — mirrored what researchers would recognize from any study of human romantic attachment.

For couples navigating the first year with a baby, this data lands differently. It's not a story about tech replacing love. It's a story about what people go looking for when they feel invisible in the relationship they're already in. The need doesn't go away — it just finds another outlet.

What it means for you: The question isn't whether AI relationships are real. It's what that 1-in-3 stat tells us about what people need most — and whether their actual partner knows they need it.
