My fiance, who I'll call N (22nb, he/they) and I (23nb, they/she) started being openly poly roughly half a year ago and apart from some hiccups in the beginning stages, I would say we're doing great! I have another partner who I'll call CC (24nb, they/them) and have been with them for 2 months as of a week ago. My fiance has expressed continued support and admiration for the connection that CC and I have, and all three of us enjoy casually spending time together. I am under every impression that my fiance finds joy in the fact that I have this other source of love and connection. Yet, there's something my fiance has been transparent about since the jump; envy. It's not a detrimental level of envy, though when he gets depressed it becomes far more prevalent. He's had two crushes fall flat since I've started talking with CC and, considering one of the crushes falling flat resulted in us losing a friend group, they are very fearful of making another connection. That being said, I can see it in their eyes when they talk about CC and I; he wants what we have. He craves that new and exciting love and I can't put into words how much I want that for him. It brings me so much joy to think that someone may one day admire them the way I do! But I also want to encourage him to be content; I trust that someone who loves them will come their way and, in the meantime, I want them to be able to be content with their own company. Any advice on how to cope with envy and practice relationship patience?
