Well, CSL, you received just an absolute gem of a reply from Kraken. One of the things that strikes me about your post is that you seem to have some questions that go beyond what the definitions of bisexual & bi-curious are. You write that you're attracted to girls probably more than guys, & you have strong feelings for your best friend, which may or may not be romantic in nature. So I have the impression that what you're really struggling with is your sexual orientation. And this is one type of thing that people often see therapists for. Do you see a therapist? If not, perhaps this would be a good idea.

I have to say that, personally, all of these labels confuse the bejibbers out of me. I'm an aging transsexual who never transitioned. And it was just a handful of years ago that I learned about the terms "transsexual" & "transgender". I was SO excited when I did because all of a sudden I had words I could use to define how I felt. So I understand the desire to have available such a vocabulary. Unfortunately many, maybe even most, of the words that define various types of gender variance don't have fixed definitions. And also, the definitions they do have can & do change over time. The words transgender & transsexual are like that. So while I do understand & support your desire to have words to describe what you feel, I would like to urge you not to get too caught up in them. What's more important is for you to sort out the feelings that lie behind your desire to clarify these words.
