The "friend zone" is men being bad communicators/straight up trying to be manipulative and thinking they can somehow move a friendship to a relationship.
Be honest about your intentions from the first time you meet.
Don't try to pull some grand switcheroo after a girl starts to trust you as a friend, sketching her out and making her feel used. Make it obvious you are after more than friendship as soon as possible, or she'll feel lied to.
I'm sorry, but it's very unlikely you will get with this specific girl. If you liked her as more than a friend, you most likely missed your chance. If you try to make a move now, you'll just creep her out and risk your friendship.
