Is it normal to not be jealous?
Yep.Totally normal
Yes, it’s completely normal not to feel jealous. People vary in how they experience jealousy, and not feeling it doesn’t mean you care any less about your partner.
Some people feel secure in their relationships, trust their partners, or simply don’t see a reason to compete for someone’s attention. Others feel jealousy more readily. Neither reaction is a required measure of how much you love someone.
If you’re genuinely comfortable with your partner’s friendships and independence, there’s nothing to fix. If you’re avoiding jealousy by ignoring behavior that actually hurts you, though, it may be worth talking about what you need and where your boundaries are.
