“But one of the most fulfilling parts of my polyamory ended up coming from an unexpected person: my metamour ― my partner’s girlfriend. For the first time in a long while, someone who wasn’t interested in having sex or falling in romantic love with me put time and effort into our relationship. She accompanied me to obscure shows my partners didn’t care for. She sweat and growled with me in the narrow staircase of my building while we pushed an antique emerald loveseat I’d fallen in love with. I held her while she cried on the train when she had issues with a partner. As I got to know my partner’s girlfriend, those old jealousy pangs became more and more sporadic because I realised she added to my life too. Our polycule — the network of my partners and their partners — spent more time together as a group: We went to one’s place for the Super Bowl, to another’s for New Year’s Eve, and a burlesque brunch for a birthday.” https://www.huffingtonpost.co.uk/entry/i-felt-jealous-of-my-partners-girlfriend-then-she-gave-me-the-most-extraordinary-gift_uk_64e87a2ae4b0c35a86bec4dd
