I know it's late but... This is when you buy something for yourself, wrap it for yourself, mark it to and from yourself and finally, not getting her anything when you do it next year!

Put your divorce papers in a box and wrap them up. On camera, open it up and serve her in real time.

I just saw a red flag go up for "Narcissist". She wants to look like she did something good in front of other people, but doesn't actually care enough to DO something good. So yeah, real strong narcissistic vibes there.

I hope you weren’t fool enough to do that for her. If she wants to go through that charade, surely she could do it herself. And finally, why is she not an ex by now?
