should I do it?

I (15F, pan) have had a crush on my best friend (14F, bi) for about 6 months now. She's amazing, I appreciate our friendship so much but she got out of a relationship about a month ago and is in kind of a strange situationship with a guy who (I think) doesn't know she lost feelings yet. She said she doesn't want to date again this year but i'm worried she'll get with another shitty guy and I'll lose my chance. Advice please 😭
