o_O; I think people are speculating too much. We don't really know anything about the family, aside from what my gay neighbor told me as a joke. Whether for the same sex or the opposite, being in a marriage you no longer care for isn't fair to anyone.
As for the bi factor, I'd consider myself bicurious. What I'd like to know is whether or not straight girls and guys would be okay with their boyfriends and girlfriends going for the same sex (while in a relationship), or if they would consider that cheating. Some really care, some don't mind at all.
