I don't know what to do, really confused...help?

No, this isn't another 'am i gay??' question, because now, I'm pretty sure that I'm bisexual.

If its relevant, I'm a girl, my best friend is a girl, capiche?

We didn't really become close friends until about six months ago. After her becoming quite drunk at a party, and then falling apart and me consoling her, we got a lot closer.

Closer as in we end up rather intertwined when we are hanging out, cuddling. We nap a lot haha.

Her mom is convinced that we're lesbians, but we've denied it, because we aren't.

One of my other friends (who recently came out to my bff, and wasn't supposed to tell anyone, but told me anyways) said that "It would make so much sense [if we were lesbians] because we're so close, and play guitar in sync and stuff".

Usually, either I'm at her house, or she's at mine, until about 11 when one of us has to leave.

So, tonight, she was over at my house. We were talking, and then we were cuddling (its not out of the ordinary in my house, my little sister and her best friend do the same thing!!!!).We do this eskimo kisses thing (noses? you know?), and then when we stopped she kinda moved and our lips were just...there. Like not kissing but touching.

Then it was really quiet, and we just stayed like that forever. But I wanted to kiss her. And we kept looking into eachothers eyes and pressing ourselves closer together, but neither of us would make the first move (way too scared, don't know what she's thinking!!). Then she had to go home, so we said goodnight and hugged when she left like we usually do, but when she said "see you tommorow?" it sounded different than it usually does.

So I'm not sure what's going to go down tomorrow. I don't know what she's feeling or whats going on, I don't have the guts to ask. And I don't want to make the first move and risk our friendship?

What the hell do I do?
