Just make sure that you are clear that she must take you seriously. That her actions today suddently have meaning. You have restrained yourself from action for 5 months. She doesn't know that. She thinks that you have simply had no reactions, either were blind or didn't care.
Spend some time pointing out the deliberate choices that you made in the last 5 months to allow her space and time. That those were deliberate choices, and that time has come to an end. From here on out, her actions will have consequences.
You have given her a false sense of security. You can't just whisk it away without preparing her for the fact that things didn't just change over night. They should have changed a long time again, but you were generous and held off til now.
