If they were polyamorous, it would mean that they had genuine romantic feelings for multiple people they were dating at the same time, it wouldn’t just be about attention, it would be about love. If it turns out they just liked attention, it’s possible that they didn’t actually have feelings for some of the people they were with and just used the fact that those people liked them to fuel their ego, get things bought for them, get attention, etc. Hope this made sense!
