Is it normal to not feel jealous in a relationship?
Yep.Totally normal
Yes, it’s completely normal not to feel jealous in a relationship. Jealousy isn’t a measure of how much you care; trust and feeling secure can mean you rarely feel it.
People experience jealousy differently. You might trust your partner, feel secure in the relationship, or simply not be very prone to jealousy. None of that means you care less.
Some people do feel occasional jealousy, and others barely feel it at all. What matters more is whether you feel connected, respected, and comfortable talking with your partner—not whether you get possessive when someone else shows interest.
