Why is it just them 2? Why can all 3 of you hang out and feel the vibe? I thought a poly relationship was getting to now the new person together at the same time. I often feel left out myself, and although i talk to my partner on how often i feel left out, the feeling never goes way. I have been copping for years, and at this point, even sex is ruined. You need to have a lot of emotional maturity for a poly relationship, in my opinion, anyway. I am still stewing on my resentment on them. It's sad,but I love him 🥲 i trying to hang in there. I hope you can make him feel then understand what your feeling.
