Is it wrong or potentially detrimental for a partner to be jealous of you?

My SO recently told me she was jealous of my recent accomplishments(career and degree wise). This really kind of hurt me because I see us as being on the same team. My personal feelings are that when you are in a relationship it’s you vs. the world not you vs. them. I guess I don’t understand because when something great happens to her or she achieves something awesome, I am genuinely happy for me as if I accomplished it myself. I feel super proud and brag on her when something great happens. This just doesn’t happen in reverse. I don’t want her to brag on me, but it makes me sad that she feels jealousy when we are on the same team here. We aren’t in competition. Do you all think this could have potentially negative effects on the relationship? Is this normal?
