There's a book called Polysecure I've started reading that's really good and should be added to this great list https://www.amazon.com/dp/1944934987/ref=cm_sw_r_cp_apa_glt_fabc_V3DWY6TB9FYT3DKEC7N7 as well as this article which really is a great resource when starting out. https://medium.com/@PolyamorySchool/the-most-skipped-step-when-opening-a-relationship-f1f67abbbd49
My nesting partner was in that exact same space when we first got started with polyamory. She would get annoyed when everyone said how easy polyamory was for women and how hard it was for men - our life was just the opposite.
There's some great advice on how to deal with jealousy and the imbalance when partner has many other partners and you don't have any in the polyamory toolkit. https://www.amazon.com/dp/1794193995/ref=cm_sw_r_apan_glt_fabc_JND5GED1219MPCYHSAA9

>Attachment theory has entered the mainstream, but most discussions focus on how we can cultivate secure monogamous relationships. What if, like many people, you’re striving for secure, happy attachments with more than one partner? Polyamorous psychotherapist Jessica Fern breaks new ground by extending attachment theory into the realm of consensual nonmonogamy. Using her nested model of attachment and trauma, she expands our understanding of how emotional experiences can influence our relationships. Then, she sets out six specific strategies to help you move toward secure attachments in your multiple relationships. Polysecure is both a trailblazing theoretical treatise and a practical guide.
Of course you want to know where the relationship is going! Your feelings are valid and should be taken as seriously as theirs. It sounds like you've been trying to keep the lines open and had been upfront about your own intensions.
I came up with a journal to help with such things like communication skills and would make a great gift for you to give hahaha
I titled it, "Don't Be An Asshole"
Well that's what polyamory means, Many Loves. If you don't have the ability to love more than one person at once that's fine. Being dishonest, being disrespectful, being uncaring and hurtful, all constitute the end of a relationship to me...I love my husband, I loved my ex, my husband love me, and he loves his girlfriend, not in the same way cause we are different people.
I ended my relationship with my ex due to his lying, his being disrespectful, and becoming uncaring and hurtful towards me. I had thought we'd spend the rest of our lives together, but sometimes people change and not for the better...paths diverge and someone you love decides the "unknown" is more exciting and worthy of their time and effort than the "known"
If you are wanting a polyamorous relationship, defining what constitutes cheating for yourselves and each other. There are lots of resources out there, like https://medium.com/@PolyamorySchool/the-most-skipped-step-when-opening-a-relationship-f1f67abbbd49 And https://www.amazon.com/dp/1944934987/ref=cm_sw_r_cp_apa_glt_fabc_3P2CW2VN8W5XWC6TFK7N Which I think may be helpful to you based on your childhood experiences.
Good luck! Remember Polyamory is no better than Monogamy, both can be legitimately loving and wonderful relationship choices. Just keep kindness, respect, and honesty as the foundations of any kind of relationship.
