Is it normal to be jealous of your friend's relationship?
Mostly.Normal for most people
Yes, it’s normal to feel jealous of a friend’s relationship sometimes. It doesn’t make you a bad friend; what matters is how you handle the feeling.
You might be jealous because your friend seems especially loved, secure, or happy—or because their relationship highlights something you wish you had. Lots of people feel a pang of comparison, even when they genuinely want their friend to be happy.
Try to notice what the jealousy is pointing to without turning it into resentment or taking it out on your friend. You can be happy for them and still have complicated feelings; those two things can coexist.
