It began, for me, as self-defense against a specific and maddening form of cruelty — the cruelty of being made to doubt your own memory.

Julian had a way, after every ugly scene, of revising it. I never said that.

You’re exaggerating.

That’s not what happened, you always twist things. And I would find myself, an hour later, genuinely unsure whether the thing I clearly remembered had occurred, because he was so calm and so certain and I was so tired.

So one day, without quite deciding to, I started leaving my phone recording in my pocket when I felt one of his moods coming on — not to build a case, not yet, but simply to be able to check, afterward, in private, whether I was losing my mind.

And every single time, the recording confirmed my memory and exposed his revision.

I was not exaggerating.

I was not twisting anything.

He was, and had been, all along.

That habit, born of a woman trying only to hold onto her own sanity, turned out to be the thing that set her free.

There is a lesson in that I have thought about often: that the small, quiet acts of self-preservation a person performs in a bad situation, long before she can imagine escaping it, are very often the exact tools that make the escape possible when the moment finally comes.

I did not start recording Julian in order to destroy him.

I started recording him in order to survive him.

And when the night came that I was ready for more than survival, the weapon was already loaded, because I had been building it, without quite knowing it, out of nothing but my refusal to let him tell me that what happened to me had not happened.
