I think that's just the normal state of things and some religions made modern society think it's no longer normal. If you can feel love for multiple people at once, and they love you back, why the fuck should you be forced to only pick one and hurt the others?

If I didn't have so many issues with being in a relationship in general then yeah I could probably date a poly person. I guess it would lower the stress for me because at least I know they won't depend on me 100% and when I inevitably hurt them it will have less consequences. I don't know if I could date multiple people myself because I don't really know what being in a relationship with each of them would really mean, since I have no experience.
