Gotcha. The fact that she's kind of floundering around seems to me that she's afraid to call herself bi like you said, which is really sad. If she likes men and women she's bisexual by definition.

Maybe you can try to causally correct her when she says everyone is on a spectrum or that everyone has a type. Plant the seeds little by little to help her realize that as someone confused about her own sexuality she doesn't get to be the authority on other people's sexualities by making statements like that. Then again, maybe she can avoid getting wrapped up in calling herself pan if she thinks everyone has a type, since pansexuals claim to 'love people, not bodies'.

I dunno. She sounds a little irritating in this regard lol.
