Is it normal to fantasize about having an affair?
Yes, it’s normal to have a fantasy about having an affair, even if you love your partner and would never act on it. A fantasy isn’t a decision or a promise to cheat.
Fantasies can be about novelty, attention, feeling desired, or simply the thrill of imagining something forbidden. They don’t automatically mean you’re unhappy in your relationship or that you secretly plan to cheat—sometimes a fantasy is just a fantasy.
People differ on how comfortable they are with these thoughts, especially if they’re in a committed relationship. What matters is what you do with them: you can enjoy a private daydream while still respecting the boundaries you and your partner have agreed on. If the fantasy is highlighting something you genuinely miss, it may be worth thinking about how to address that honestly rather than acting behind your partner’s back.
