I could use some help/advice. I've never been in a relationship before, nor have I wanted to. But a few months ago, I met someone I really love. And they love me. The only problem is they're Poly, and I'm not. I went into it knowing this,.and I don't have an issue with it. But I can't help but feel terrible, like really bad, anytime they're around another partner. It's not all the time, and I like their partners, it usually flares up terribly when they show affection towards each other. Maybe it's jealousy, envy, or possessive love, but I could use some help working through this. Have any Mono people been where I am? I refuse to give up on this relationship, so I want to see what, if anything, I can do to stop feeling like this.
