Make no mistake, she absolutely WILL test your boundary. Especially if you don't have a strong track record of enforcing them successfully with her. She might use every trick at her disposal, too, swinging wildly from super-duper-nice (and even trying to get you to ML), to vile SPEW ("Well, I *WAS* going to consider coming back and working on a monogamous marriage with you, but NOW YOU'VE BLOWN IT!!"), to pretending to "cool it" with her OM, and back again.
Expect her to be all over the map, as you two establish a new power dynamic and equilibrium between you, and she tests you to see what "works" to get you back dutifully in line.
