Everything you said here was so good honestly.

I am extremely happy whenever my partners find someone who can help make them as happy as I try to. I want my partners to have the happiest possible life ever and it's unfair to everyone involved to stop them from being able to get that happiness.

I think something a lot of monogamous people forget when talking about poly is that jealousy is a pretty natural thing to happen... Even in polyamorous relationships.

I've felt jealous before in my situation, the difference is that I talked with my partners and found a good solution and set of boundaries that made everyone happy vs trying to control their time and life.

I said this in another comment but the most loved I've ever felt was when my fiancé helped me pick out my outfit for my first date with my bf (who I'm also to a year with!!). I also love helping them both with their relationship struggles and life issues and so on. I love them both tremendously.
