Unless you like repeating the process over and over of how it felt when she cheated on you, stop responding to her.
I would even let her know by saying "You know, I appreciate you reaching out, but this just doesnt feel right for us to be talking after what happened and I think I need to keep moving in a different direction. Take care."
Chances are she will get p!ssy through a final reply, but dont budge. She is only mad because she isnt manipulating you and cant get your attention by feeding you bread crumbs.
The other option is this, if you want to only fvck her again: "Clearly we are not good for each other in a relationship, but if you want to come over and have a drink and hook up, let me know".
Only do that IF you can handle the balance of fvcking her without getting attached to her. Its also a slap in her face that you only see her as a piece of @ss at this point and is a win/win for you if she comes back with "Oh is that all I am to you"..........
"Yep, after you cheated on me, thats all we can be....fvck buddies".
If she bites you get laid. If she doesnt, you emotionally win because you just put this chick down 20 notches on the totem pole and she knows it.
