Is it normal to think about other girls while in a relationship?
Yes, it’s normal to sometimes think about or feel attracted to other people while you’re in a relationship. What matters more is how you act on those thoughts and whether they’re getting in the way of the relationship you want.
Being with someone doesn’t switch off your ability to notice other people or have a passing fantasy. That doesn’t automatically mean you love your partner less or want to cheat; thoughts aren’t the same thing as actions.
People draw different lines around what feels comfortable, especially when it comes to flirting, sharing fantasies, or keeping things private. If these thoughts are taking up a lot of your attention or pointing to something you’re unhappy about, it may be worth thinking through what you want and having an honest conversation with your partner.
