Is it normal to be jealous in a friendship?
Mostly.Normal for most people
Yes, feeling jealous in a friendship is normal. It can pop up when you feel left out, replaced, or worried the friendship is changing; what matters is how you handle it.
Friendship jealousy happens to lots of people, even when they genuinely want their friend to be happy. A new close friend, less time together, or feeling left out can bring up a fear that you matter less than you used to.
The feeling itself doesn’t make you a bad friend. Try to notice what’s underneath it and, if something’s bothering you, talk about it without blaming or trying to control who your friend spends time with. Jealousy is a feeling; it doesn’t have to drive the friendship.
