I got my answer today.
I just couldn't wait any longer, so I called her and asked, if she had time to think (we didn't have any opportunity in school to talk alone, so the phone was the only possibility).
I've read to much where nothing was. I am just a friend for her, nothing more.
I did somehow expect this, (I don't think she would have needed seven weeks to tell me that she did love me too, so I think she waited so long because she didn't want to hurt me) but I still had hope.
But knowing is still better than not knowing.
Now I have to try to not ruin our friendship by griefing to much.
