Is it normal to think about someone else while in a relationship?
Mostly.Normal for most people
Yes, it’s normal to think about or feel attracted to someone else while you’re in a relationship. A passing thought doesn’t mean you love your partner less or need to act on it.
Being in a relationship doesn’t switch off your ability to notice or imagine other people. Thoughts and passing crushes happen to lots of people, and they don’t automatically say anything dramatic about how you feel about your partner.
What matters more is what you do with those thoughts. People draw different lines around flirting, secrecy, and emotional intimacy, so it’s worth paying attention if the thoughts are taking over, pointing to something you’re missing, or nudging you toward behavior that would break agreements with your partner.
