Is it normal to fantasize about someone else while in a relationship?
Mostly.Normal for most people
Yes, it’s normal to fantasize about someone else while you’re in a relationship. A fantasy doesn’t automatically mean you’re unhappy or want to cheat; what matters is how you choose to act.
Lots of people in relationships still notice other people or have fantasies about them. Your mind can wander without it being a verdict on your partner or your relationship—and a thought isn’t the same thing as a plan.
People differ on whether they’d want to hear about a partner’s fantasies, so there’s no need to share every private thought. If the fantasy keeps pulling your attention or points to something you’re missing, you can use it as a cue to reflect or talk with your partner about your needs, while keeping whatever boundaries you’ve agreed on.
