I would place the souvenirs on the kichen counter. Look her in the eye and tell her, "I don't think I made my point. It's disrespectful for my wife to hold onto these things. I will show you mercy this one time. Either you give them to me to get rid of or you can pack your stuff now. Am I being clear in what your choices are?"

"I have decided where I stand, now it is time for you to decide."

Then say nothing, give her a minute to decide. If she starts talking, defending etc. Just say two words - "Choose now."

If she hands it over then listen, validate and show mercy.

If not you help her pack.

Retain faith that you will prevail in the end, regardless of the difficulties and at the same time confront the most brutal facts of your current reality, whatever they might be.
