Let’s kill a myth right now: this isn’t about how well you cooked, how good the sex was, how much you gave, or who they’re attracted to. A person built to cheat will cheat in a relationship where they’re starving for attention, and they’ll cheat in a relationship where they’re getting everything they could ever ask for. The variable was never you.
And let’s kill the second myth while we’re at it: bisexual people aren’t “more likely” to cheat. Gay men aren’t “wired for chaos.” Straight men aren’t excused because “that’s just how they are.” None of that holds up. What actually predicts infidelity has nothing to do with who someone is attracted to and everything to do with who they’ve decided to be.
The Comfortable Lie We Keep Telling
It’s easier to blame a category than to sit with the truth: cheaters cheat because of what’s happening inside them, not because of what’s happening inside their pants or who’s on their dating app filters. Blaming sexuality is a shortcut — it lets people avoid the harder conversation about entitlement, impulse control, and unresolved emotional debt. It also does real damage. Every time infidelity gets pinned on bisexuality specifically, it reinforces a stereotype that’s been used for decades to paint bi people as inherently untrustworthy in relationships. The data doesn’t back that up. Character does the predicting — not orientation.
It’s Also Not About You
The other lie, usually aimed at the person who got cheated on: “if you had done X, Y, Z, they wouldn’t have strayed.” Cooked more. Weighed less. Given more attention. Argued less. This is one of the oldest tricks in the book, and it puts the burden of someone else’s integrity on the person who was betrayed.
Here’s the truth that doesn’t make it into most conversations: a person who is committed to fidelity as a value will hold that line even in a relationship that’s struggling, boring, or going through a dry season — because for them, the commitment isn’t conditional on your performance. A person who isn’t committed to fidelity will find a justification even in a relationship that’s thriving, because the itch was never really about you. It was about permission they were looking to give themselves.
What Actually Predicts It
Research on infidelity keeps landing on the same handful of factors, and none of them are sexual orientation:
Opportunity meeting low restraint. People with weak impulse control and easy access to temptation — proximity, privacy, attention from someone new — are more likely to act on it, regardless of who they’re attracted to.
Entitlement. Some people quietly believe the rules of monogamy apply to everyone except them. That belief usually isn’t announced. It shows up in action.
Avoidant attachment. People who struggle with real intimacy sometimes use infidelity as a release valve — a way to create distance without having the harder conversation about what they actually need or don’t want.
Unresolved personal dissatisfaction. Not dissatisfaction with the partner — dissatisfaction with themselves. Cheating becomes a quick hit of validation for something that has nothing to do with the relationship at all.
Notice what’s missing from that list. Not one of those traits belongs to a specific sexuality. A person can be straight, gay, bi, or anything else and carry every single one of these patterns — or none of them.
A Cosmic Lens, Because the Sky Doesn’t Lie Either
If you want to bring the stars into it — and you know I will — this isn’t a Venus problem, it’s a Saturn problem. Venus governs desire and connection; it doesn’t govern discipline. Saturn does. Someone’s Saturn placement — how they handle responsibility, restraint, and consequence — tells you far more about whether they’ll hold a boundary than their Venus sign ever will. A person with an undisciplined Mars, prone to impulsive action, paired with a poorly integrated Saturn, is a much stronger predictor of straying than any placement tied to who they’re drawn to. Character transits, not attraction transits.
The Real Test
If you want to know whether someone is capable of fidelity, stop asking who they’re attracted to and start watching how they handle small moments of temptation and accountability. Do they tell you when something made them uncomfortable, or do they hide it? Do they take responsibility when they mess up, or do they reroute the blame? Do they respect boundaries when no one’s watching?
That’s the real audition. Not their sexuality. Not your cooking. Not your body. Their character — full stop.
Bottom Line
A person who’s going to cheat will find a reason, an opportunity, and a justification no matter what you do and no matter who they’re attracted to. And a person who’s committed to integrity will hold that line under pressure, boredom, distance, and temptation — because that’s who they decided to be before you ever walked into the picture. Stop interrogating sexuality. Start paying attention to character.
