So me (19, genderfluid) is dating my partner (19M) online, since we are long distance atm. My partner is also dating someone, who we can call Prima? (18M) and Prima has a partner, Lauren, (19M) too. When I asked my partner out we both knew we were polyamorous and it wasn't much of an issue, but a few days after me asking out my partner, Prima asks them out as well, I gave my consent at the time and it was all fine and dandy but there wasn't much thought behind it?

Now me and my partner have a beautiful relationship where we are overly protective of each other and he isn't fine with the idea of me dating around and after a while of thinking I realized I wasn't either, but I feel very off about Prima, while Prima is nice and all, they have a lot more dates with my partner and group gaming sessions with Prima and Lauren and all.

The main reason for this is timezone stuff, we've communicated about this and they've assured me that they love me and I would never be secondary yet I still can't get. over it? It makes my skin crawl, I'm used to triad or group polyamory but this particular relationship of Prima and my partner rubs me the wrong way and makes me fear that I'm secondary?

I know feeling jealousy in a polyamory relationship is normal and I'm happy they feel happiness with their partner but eugh idk how to explain this any better.

We use the 'structure' way of relationship in our poly relationship? like me and my partner are one structure, while prima and lauren are another, it's just that prima and my partner are like a 'connecting link' between the two relationships, while it makes me happy that me and my partner are 1 structure i can't get over it? i'm really scared because I really do love my partner a lot and don't want to lose him and prima and lauren are such amazing people too
