NC for good

Does anyone feel this way? I’ve gone NC for 6 months before so being 7 week out doesn’t really feel like much of an accomplishment. In the back of my mind, I know the heroine is out there, will always be out there, it’s just a text away. That really scares me. One insane moment of magical thinking. That’s what has happened in the past and the rollercoaster starts again. What can I do for myself to know it’s done and over forever? Any thoughts?
