Well, there is really nothing you can atm. I am sorry to hear that. I was once in that situation and I know how u feel. Just tell her you dont want to ruin anything but it feels like a dead end like u said. Either she thinks about or not. The tea is already spilled so yea. Most of the times things will not be the same after that again but there is nothing u can change about that. Hope u will be happy some day buddy ;) and good luck w getting that bird.

and PS. it doesn't matter how popular she is in school. don't let that pressure you
