As Jesus said, "resist not evil." Turn the other cheek.
Don't do this as a victim. Don't do this with the arrogance of a perpetrator. Simply "be" there and don't play their "game."
Take 100% responsibility for their bullying. When you do that, there's no room for "blame." Responsibility is entirely positive and an act of creation; blame is entirely negative and an act of being at effect.
Don't cower. Look them in the eye. If they strike you, turn the other cheek and look them in the eye again. For most bullies, that takes all the "fun" out of it. Be fearless and you expose their fear.
