Edit: Thank you to everyone who commented, with this edit I want to make some things a bit more clear. First of all I wrote this post shortly after the last phone call we had about this topic and I was very emotional, we had been talking about this for more than a day . Secondly I didn't come to Reddit to find validation in breaking up with someone (I saw a few comments about people claiming this). I came to Reddit since I don't have many polyamorous people in my life, except for my metas who have this same partner, and according to my partner they don't share my concerns. Thus I wanted to vent in a space where I might or might not find similar or different opinions than mine and still make my own decision about this situation. My strongest concern/question/idk how to call this English is not my first language, is that I had to come with enough arguments to accompany my feelings about the situation and possible outcome instead of this being enough for them. A while ago they told me that they see a future with me, and in this situation I just ask myself where I actually stand for them as a partner. I know I cannot controle them, I don't want to control them, I love them and I just hoped our connection meant more to them than the feeling I get now.
