These are all GLs if you don’t mind reading them, though it's been a while since I've read them so I don't remember if they all love each other equally or if it's a situation where one character has two girlfriends who only like her:

Haven't read this one but this was a love triangle situation where girl 1 loves boy, boy loves girl 2, girl 2 loves girl 1 that ended in a poly relationship, but again not sure if they love each other equally or not:
