Not at all, sunsets. She has no right to know how you are doing, just as she has no claim to you for friendship or anything else down the line.
I'm so glad you made it through the anniversary and that it wasn't as bad as you thought it might be. I am skeptical that she had remorse - more likely regret, but either way, you held to your boundaries, kept her at arms-length, and most importantly, protected yourself. Well done.
