I recently visited my partner's(non-binary) friends for the first time, of course with my partner. To be honest I have no clue if I was overreacting and just feeling insecure but I do know I got sad. At times it felt like I was thirdwheeling or as if I wasn't even there. Some background, we flew to visit their group of friends because three of them were graduating over the weekend so my partner of course was going to support them and I was asked to attend as well and I wanted to go to, to meet their friends and to spend time with everyone. Their best friend has been in my partner's life for almost eleven years and every time this friend walked into a room it was like my partner would forget about me and be drawn to this friend, it made me feel sad and like I was just being left behind. And as they would talk I would realize that eleven years is such a long time and i started to feel so insecure because we've been together for a year and I cant imagine someone caring about me the way that my partner and their best friend cares for each other so it just made me so sad and like I wasn't good enough to even keep my partner's attention. Is it unrealistic for me to want to be prioritized in this situation? I feel like I am being dramatic and overthinking it, and I don't know how to express these feelings without possibility hurting my partner's feelings, but i hate feeling like this. Do you have any advice to stop feeling this way or how to communicate this with them?
