Every time I read a women’s website or magazine these days, I come upon a headline that demands to know, “IS THIS CHEATING?!?!” Is sending flirty Facebook messages to someone else cheating? Is sending them nude pics cheating? Is flirting cheating? Is there a chance you could actually be cheating on your boyfriend and not even realize it?

Technology seems to exacerbate these existential questions because it keeps giving us new ways to violate our partners’ trust (but, on the flipside, it keeps giving us new ways to be sexual). Coming up to someone in person and stripping naked is one thing; sending a nude photo of yourself to them is another (or feels like another). And so we have to have these endless conversations about what exactly cheating is.

Here’s the thing, though. If you’re reading a magazine article to find out if you cheated or not, you’re doing it wrong, because it can’t answer that question for you. The only person who can tell you that is your partner.

Nobody else can tell you what “cheating” means in your particular relationship because it’s different in each one. In monogamous relationships, most people take the “default” definition of cheating, which includes any sort of sexual contact with someone else. But even then, what about flirty Facebook messages? What about “emotional cheating,” when you have feelings for someone else (even if you don’t act on them)? Some people count these things as cheating; others don’t.

Monogamous relationships can have a lot of wiggle room, too. I’ve known many couples in which one partner is straight and the other is bisexual, and the straight partner doesn’t mind if the bisexual partner hooks up with people of their own gender (as long as it’s just hooking up). Long-distance relationships can also have certain “rules” for what the partners can do while they’re apart.

In non-monogamous relationships, there’s an even greater variety of configurations and definitions of cheating. Some couples restrict which types of sexual acts they can do outside of the primary relationship, or they specify that sex without barriers outside of that relationship would be cheating. Some people form triads or group marriages and forbid all sexual contact outside of that established group. Some decide that you can only hook up outside of the relationship at certain events or in particular spaces, or if your primary partner is present and either watching or participating.

Meanwhile, in other non-monogamous relationships–for instance, mine–the boundaries aren’t about specific acts or people, but rather about communication. If my partner or I act secretively about other people we’re seeing, we’re cheating. If we’re not considerate to each other in terms of making plans with those other people, we’re cheating.

But people don’t just come to these agreements by separately reading Cosmo articles about what cheating is and then never discussing it.

So, if you’re unsure of what counts as cheating in your relationship, you have three options:

1. Say nothing and avoid all activities that could possibly be considered cheating, thus potentially missing out on some great opportunities;

2. Say nothing and do whatever you feel like doing while convincing yourself that your partner wouldn’t see it as cheating, thus potentially, you know, cheating on your partner;

3. Ask your partner what they would like the boundaries of the relationship to be.

I can see why that third option might feel awkward or uncomfortable. If you ask your partner, “What are our boundaries as a couple? What could I potentially do that would make you feel like I cheated on you?”, there’s a chance that your partner will interpret that as you “looking for permission” to get involved in some way with other people. But if they understand the importance of communication in relationships, they’ll see it for what it is–an attempt to make sure that you’re on the same page and that neither of you will be hurt by a misunderstanding about relationship boundaries.

That’s also why it’s a good idea to have that discussion at the beginning of a relationship rather than once it’s been going on for a while, but late is definitely better than never.

The great thing about a discussion like this is that it also allows for discussing things that aren’t “cheating” per se, but nevertheless feel like a violation of boundaries. For some people, it’s not “cheating” if their partner flirts harmlessly (as in, with no intentions for anything else) with someone else, but they wouldn’t feel comfortable if their partner did that right in front of them. For some people–it’s hard for me to imagine this myself, but I’ve heard of it–it feels “wrong” somehow if their partner dances with someone else at a party. Some people would want to know if their partner develops a crush on someone else, but that doesn’t mean it’s “cheating” if they do. Nevertheless, finding out that their partner has been keeping a new crush secret would feel like a violation of trust.

All of these nuances can be made clear by a conversation about boundaries.

Prescriptive definitions of cheating (i.e. “this is what cheating must mean for everyone”) don’t serve anyone. They keep people stuck in a very restrictive version of monogamy (not that there’s anything wrong with monogamy, as long as you consciously choose it). They allow for misunderstandings that hurt people, such as when one partner thinks flirting with others is okay and the other feels like it’s cheating. They prevent people from creating their own relationship models that work best for them, and encourage them instead to conform to the dominant cultural conception of what a committed, “faithful” relationship is.

Edit: A reader and fellow blogger, Patrick, noted that the part of this post that deals with relationships between straight and bisexual people might be reinforcing the stereotype that all such relationships involve an agreement that the bisexual person can hook up with others of their gender. I definitely don’t want to reinforce that stereotype, so I asked him how I might have rephrased that in a way that was clearer and less stereotype-y. He suggested this:

“I’ve known many mixed-orientation couples (one partner is straight and the other is bisexual), and in some of them the straight partner doesn’t mind if their partner hooks up with people of their own gender (as long as it’s within their negotiated boundaries).”

I like this phrasing a lot more, so I decided to append this here. A huge thank-you to Patrick for pointing this out and suggesting an improvement. 🙂
