hmm im not sure i have any fro the persepctive of whos choosing. that seems unrelatable to me as a dilemma compared perhaps to competition (such is toxic monogamy/jealousy culture rip lol) or simply having a mnage a' troix. so:
nina simone version of ""theother woman" is incredible. but so was everythign nina even breathed near..
britney spears - 3brandy & monica - the boy is mine
"caught up" is a concept album by millie jackson about adultery from 2 diff perspectives :)
sorry i cant think of anything specifcially about making the CHOICE off the top of my head but there r plenty of copmlex dynamics in situations like this to explore. <3 cheers x

It's about the singers polyamorous relationship between him, his wife and a Japanese woman they've met. It suddenly ended when her visa expired and both the singer and his wife got very lovesick about it.
