My girlfriend has three other girlfriends (two of which are together and living with each other) and an aromantic sort-of boyfriend/moirail/quas i-platonic life partner who is also my aromantic sort-of boyfriend/kismesis/bes t-frienemy-with-benefi ts... He also has four other relationships. I'm not certain how he defines them. We're all allowed to have other romantic and sexual relationships outside of the existing ones.
The three of us that form my open triad have considered living together. They've already lived together for a while.
I love them both so much I don't have the words to say.
(P, dude, if you find this, don't freak out, I'm still not romantically into you. <3< )
(A, I most definitely am. <3 )
