In My Judgment.
"she likes to think she is all logical and shit...."
When did you figure this out ?
Is this a sudden flash of insight, or did you know/suspect this all along ?
The revenge thing is just laying waste to what happened and those involved.
If you want the hurt to pass and to move on to better things, it may get in the way. You will likely never hurt them the way you were hurt, because they don't have the 'code' you have to be shocked and cracked.
You can only hurt them in fantasy, or reality in the way that hurts them. That is not even an 'eye for an eye'. It is just a beatdown...and you already did that.
What is interesting is that place in you that is hurt and angry, is also "IMJ" hurt and grieving. If I'm right, you must take that to someone who understands...someone close enough to you to hear what it feels like to lose what you lost. If you want to move on, the dark valley of pain is the one you have to walk through slowly...maybe with a sister, mother, understanding friend of yours ?
Living well is the best revenge, really.
