I 15M am in love with 15F but confused?

For some context I met this girl let’s call her Liz off one of my hgs at school. Now me and Liz have been talking for about 2 months now and genuinely I fell for her to the point where I offer to walk her to classes, I gift her gifts, I write her paragraphs and letters and such.

But the problem is the same hg who presented me Liz also told me that Liz was waiting for her junior year to get into a relationship.

Now I have flirted with Liz and she has noticed and has told he before that she wants to be friends only BUT later on idk if it’s bc how we get along or something but she started flirting with me n stuff (or something I think) and now I’m confused since she says stuff as “I love you” and we’ve opened up on intimate stuff and I really don’t know what position I’m in or what to do. Rn I’m thinking of giving her some chocolate and flowers for valentines but I’m genuinely confused on what position I’m in or what zone. Am I in the friend zone or the friends with benefits or situation I’m not sure. And I’m too scared to ask her what we are and too scared to tell her how I feel towards her.

I need advice on this so bad since I’ve been breaking my head on this for ages now 😭
