He is confused...

My best friend is counfused about me and his best friend. But he doesn't know that I know this information, he is also bisexual, I'm a girl and his best friend is a guy (I don't know him) one of my friends (and his) told me that his friend treats him like crap and I'm naturally sweet with everyone and she thinks that I'm better for him. But I don't even know how to feel about this or if I even like him.
... Do any of you had some advice? Thanks x.
