I so understand where the need to remove her things from your room came from. I have been there. I took down every photo of H when he MO. I didn't say anything, but I placed them all, still in their frames, in his wardrobe at the front where he would see them. He took these photos to his flat with him. I assume he has them in a drawer somewhere.
When 7 months later I found out he had started dating, I went into every drawer and photo album and shredded every single photo of us from before we had children. I kept the ones post kids as (even in my madness) I knew the kids would want these someday.
A part of me wanted him to know what I had done. To hurt him as much as he had hurt me. To show that I cared as little about our shared memories as he did. This is not detachment. Detachment is living the fullest life you can without caring either way how your actions impact her. It is to get to place, where her actions no longer impact you.
If you moved her things so you have a place which is just yours, away from the madness of everything, then it was the right thing to do. But if you did it purely to get a reaction, then you are not yet detached.
I would not mention it to her at all.
I found out recently (from our cleaner who saw him put them in his car) that he had been in the MBR for 2 hours before with the door shut and when he came out his eyes were red and he looked devastated. This did not bring me any satisfaction. Like many things I have done out of anger or spite, I wish I had not done it.
