Is having an AI girlfriend cheating? What the surveys show and how couples decide

What the surveys say

No survey settles the question, but several large ones ask it directly, and they land in a similar place: a sizeable minority says yes, a similar share says no, and many are unsure.

So roughly one person in three to four in ten would see an AI girlfriend as cheating. If your partner is in that group, the label matters less than the hurt. More survey data is on our AI girlfriend statistics page.

Use is highest among younger adults. In the Match study, 33% of Gen Z singles had engaged with AI as a romantic companion, against 16% of all singles, and in the Wheatley data young men were generally about 5% more likely than young women to engage with an AI companion. So the question is most likely to come up in younger couples, often when one partner uses these apps and the other does not.

Where people draw the line

People who answer "it depends" usually mean one of three things.

Sexual content

For many, 18+ chat or explicit roleplay is the line, because it looks like sexting someone else even if nobody is on the other end. Most AI girlfriend apps allow it (29 of the 31 in our data), so for most users this is a live question, not an edge case.

Emotional intimacy

Others worry more about feelings: telling the AI things you do not tell your partner, turning to it after an argument, or saying "I love you" and meaning it. In the Wheatley survey, 68% of regular users said it was easier to talk to their AI companion about their feelings than to real people, and 50% wished their real-life partner behaved more like their AI companion.

Secrecy, time and money

The third view says the app is fine and hiding it is the betrayal. The same goes for hours spent in the app instead of with your partner, or money spent on tokens from a shared budget.

These are the same three lines people use for affairs with other humans: physical, emotional and hidden. If you and your partner already agree on what counts as cheating with a person, that agreement is the best starting point for an AI companion too.

Secrecy is what the research flags most

The strongest finding in the 2026 Secret Soulmates report from the Wheatley Institute and the Institute for Family Studies is not how many people use AI romantic companions but how many hide it. Among 2,431 young adults who were dating, engaged or married:

• 1 in 7 (15%) regularly interacted with an AI romantic companion, and another third (34%) had used one at some point.
• 30% of users said their partner had no knowledge of it, 11% said their partner was only somewhat aware and 14% said mostly but not fully aware.
• Where partners did know, users estimated the partner knew about only 37% of their actual use.
• 69% said it was somewhat or extremely important that their partner not learn the full extent of it.

The report's authors argue that this kind of hidden use makes real-life relationships less stable. Whatever your view on AI companions, hiding one is the part most likely to feel like a betrayal when it comes out.

When an AI girlfriend is more likely to hurt a relationship

Using an AI companion does not automatically damage a relationship, but some patterns are warning signs:

• You hide the app, clear the chat history or use it only when your partner is asleep.
• You compare your partner to the AI, or wish they were more like it.
• You turn to the AI instead of your partner after an argument or bad news.
• You spend money on tokens or upgrades that you would not want to explain.
• Time in the app is replacing time together, sleep or friends.

Research on heavy use backs up the last point. A four-week MIT Media Lab study of 981 people found that those who chose to use a chatbot more reported more loneliness and less real-world socializing. If spending is part of the problem, our AI girlfriend cost guide shows what the apps really charge each month.

How to talk to your partner about an AI girlfriend

1. Bring it up before they find it. Discovery turns a conversation about an app into one about trust.
2. Explain what you use it for. Company when you are apart, practice, a story or 18+ fantasy: be honest, because the answer changes how your partner will feel.
3. Ask where their line is. Sexual chat, pet names, daily use and spending are all fair to discuss. Do not assume their line matches yours.
4. Offer to show them. Worries often shrink once people see what the app actually does. Sometimes they do not, and that is useful to know too.
5. Agree on rules and revisit them. For example: no explicit chat, no spending over a set amount, or none of it while you are both home.
6. Be ready to stop. If it is causing real pain, canceling takes a few minutes. Our guide on how to cancel an AI girlfriend subscription covers every payment method.

If you are single

If you are not in a relationship, there is nobody to cheat on. An AI girlfriend is then closer to a video game or a romance novel: entertainment, company or a way to practice conversation. Our guide to what an AI girlfriend is explains how the apps work.

Two things are still worth keeping in mind. First, future partners may have views: in the Singles in America data, 40% of singles would count an AI partner as cheating once a relationship is exclusive, so it is worth mentioning early. Second, research suggests AI chat helps in the moment but does not replace people. Harvard Business School researchers found the relief from a daily 15-minute chat with an AI companion did not build up over a week.

Setting boundaries inside the app

If you and your partner agree that some use is fine, the app itself can help keep it within those lines:

• Write the character as a friend. In apps with a character builder (27 of the 31 we track), the relationship description decides whether she acts as a girlfriend, a friend or a practice partner. Our AI girlfriend prompt guide has templates you can adapt.
• Turn off notifications so the app does not pull you in at dinner or late at night.
• Cap spending. Stay on a basic plan and skip token packs, or pay with a card that has a limit.
• Agree on a time window, such as a commute or a trip when you are apart.

If your partner is curious rather than worried, many of the same apps offer male characters too. Our list of AI boyfriend apps covers them.
