Young and poly...advice please

Elliot • Hey I’m Elliot I’m nonbinary I’m pansexual and polyamorous but I prefer the term Queer 🏳️‍🌈

Hey, I need some advice.

Quick bit of info I’m non binary, Queer and poly I’m 16 ( 17 in 2 months) and my partner is a trans man who is pan and poly (he’s 18)

A few months ago my partner and I talked about our relationship being open as we are both poly. He started to like someone from his college and I accept it in the beginning I was really happy for him. Until the girl he was with tried to push me out of the picture because she decided she didn’t want to be poly but wanted him. So they broke it off and we went back to being mono. It really really hurt me for some reason and still affects me now, I’m very bitter and angry at how she then went on to treat me, and he still goes to college with her.

At my college a girl in my drama and theatre class asked me out on a date and I’ve told her that I’d have to ask my partner first so we can set out some rules and see where things go. And he’s being really funny with me he said I can go on the date and asked to see a picture of her so I showed him and he said she wasn’t very attractive. Which stung a little cuz I think she’s cute as hell! They are going to meet before we go on the date because that’s what they want to do and I’m more than happy for that to happen.

We also set up my partner on a dating site because he’s 18 and he is talking to some guys so I’m also really happy for him but I want time between him and I as he is my primary partner to stay the same.

Is there anyone who is older than me (17)and also in a polyamorous relationship that could give a baby queer some advice on how to navigate feeling jealous and happy at the same time and working out how this all works!

Thanks to anyone that replies 😊
