i am more sympathetic with her brother than her.
i know she was lied to at first but i think it's gross to knowingly share a man.
she was disgusted at the one dude for dating multiple women but is fine with this man going home to his wife everyday? it just doesn't make sense. it just shows she is selfish and wants what she wants period. i do not sympathize with the victim of a whorerish man's ways angle at all.
the wife is doing the same thing, sharing, but for now she is legally bound to him and financially intertwined. she can't just cut things off so easy, although should end things as well based on the emotional abuse alone.
