Is it a good idea to send notes to one of my friends to get her away from the guy i like and tell her that i keep finding them in my binder
It is not a good idea. You might like the guy but he does not like you back. Writing a note will just complicate issues and make you lose a friend or destroy any hopes of ever dating that guy.
No, because they will both be mad at you when they find out you are lying. Also, it is mean and would hurt your friend.
no i would just have a talk with your friend about it.. i no it can be hard to talk about it or embarresing or whatever but if you both like him you both need to be on the same page:)
