Forty-one percent of Americans now count an ongoing flirtatious text conversation as cheating, according to a nationwide 2026 survey of 2,000 adults from Talker Research, reported by Deseret News. Thirty-seven percent say the same about keeping a dating app active “just to look,” or saving an ex under a fake name in your contacts. None of those categories of betrayal existed a generation ago, because the technology behind them didn’t exist either. What’s changed even more than the technology is who’s doing the judging: on several of the murkiest habits, the youngest adults surveyed turn out to be markedly harsher than everyone older than them, not looser, which flips the usual assumption that a more permissive generation writes more permissive rules.
For most of the modern dating era, the definition of cheating rested on one unambiguous act: sex with someone else. Nearly everything else sat in a gray zone couples negotiated privately, with no real national consensus behind it. When YouGov and the Institute for Family Studies ran a national “iFidelity” survey of married and formerly married adults, the gaps in that gray zone were wide. Only 42% of respondents called flirting a form of infidelity on its own, just 32% said following an ex on social media counted, and 30% flagged pornography use as cheating, according to the Institute for Family Studies’ analysis of that data. The behaviors existed. A shared verdict on them didn’t.
The List Got Long
That verdict looks different now. The 2026 Talker Research survey found nine separate digital habits that a third or more of respondents classify outright as cheating: keeping an ongoing flirtatious text exchange (41%), sending late-night messages meant to stay hidden (40%), keeping a dating profile active “just to look” (37%), saving a contact under a fake name (37%), deleting messages before a partner can see them (36%), staying in secret contact with an ex (36%), meeting someone new one-on-one without mentioning it (36%), keeping up a friendship a partner doesn’t know exists (34%), and sending romantically charged compliments or heart emojis (33%). A single physical line has turned into a checklist with nine or more entries, and most of the items on it leave no visible trace at all.

The Age Reversal Nobody Predicted
The generational pattern inside that survey doesn’t match the stereotype people reach for first. Gen X and Boomer respondents, per the Deseret News writeup, were far more likely to say those small acts would actually end a relationship than Gen Z respondents were, meaning older adults judge the fallout of micro-cheating more harshly even as younger adults are the ones expanding what counts as cheating in the first place. A separate, earlier national poll from YouGov’s own crosstabs shows that same split behavior by behavior. Asked point-blank whether flirting with someone else counts as cheating, 65% of adults 18 to 29 said yes, compared with 47% of adults 65 and older, an 18-point gap that runs the opposite direction of what you’d expect if younger couples were the casual ones. The same crosstabs show 18-to-29-year-olds narrowly out-flagging seniors on holding hands with someone else, too, even though the oldest respondents remain stricter on unambiguous acts like sex, nudes, and suggestive messages.
Part of the explanation is architecture, not values. A flirtatious group chat, a secret finsta, a dating app kept open “just in case,” a contact saved under a fake name so a notification doesn’t give anything away: these are habits that simply didn’t exist for a couple dating in the 1990s, so no earlier generation ever had to rule on them one way or the other. Younger couples, who do most of their relating through a phone screen, have had to build a rulebook for behaviors their parents never encountered, and survey after survey shows they’ve built that rulebook more expansively than anyone expected. It isn’t that they’re policing each other harder for the sake of it. It’s that a text thread now carries the emotional weight a phone call used to, so the same rules that once applied to phone calls have simply migrated over.
None of this means younger couples are more suspicious or more fragile than the couples who came before them. It means the boundary of a relationship has moved from the bedroom to the group chat, and the people who live inside that group chat all day are the ones setting its terms. If you’re dating someone from a different generation, the mismatch worth naming out loud probably isn’t how loyal either of you is. It’s how long your personal list of “that counts” actually runs, because two genuinely faithful people can still be operating off two very different lists without either one realizing it until something on one list gets crossed.
