No. I think she is just expressing her sexuality and also using it as a way to rebel against all of the rules and strictness that Shadowhunters have to deal with from the Clave and their own parents.
Ummmmmmm, no, i guess. I think she's the best character ever. But when anda put it that way, it slightly fits her (hmm, how to put this...)way of life. ****Sigh****. I guess she kind of is.
Not really. I tend not to throw those kinds of labels around. She did sleep around and had a lot of boyfriends, but it wasn't like she was cheating on any of them. I actually think most of them were as interested in no-strings relationships as she was.
As an earlier answer points out, she was behaving that way as a means of rebelling against her parents and the Clave and general expectations. I also think it was a way of deflecting attention away from Alec.
