When my best friend came out to me about the UN scandal, I went in defense mode. I reasoned, "There must be a logical explanation".
As time passed, the seed he planted had taken root and grew quickly.
Don't give up on your friend. It may take a while, but she may surprise you and actually look into what you dropped on her. After all, any ex-JW had to take some sort of initial step to get where they are today.
