How would I prove this???

My girlfriend and I broke up last weekend. This time, for good. Anyway, we were at my house when I told her that I wanted to end it. She said "fine" and ran back up the stairs for something. She came back down with MY electric razor (but not the charger), a framed picture of my last car (91 GT) and my current car (89 GT), then she went into the garage and took a framed airbrush of my 91 GT, and she also took two liscense plates that were airbrushed and framed. Here's the problem... All of these things were gifts from her to me (except the razor. I bought that with my own money) I got the big airbrish (91 GT) for chistmas last year and I got the other things this year for christmas and my birthday.

These pictures meant alot to me (thats why they were all framed) and now she refuses to give them back. Hell, she said the only reason she took the razor was so I couldn't use it...WTF?!? Anyway, I want to try and get my stuff back but I don't want to get into a war with her. Should I try and get it back or should I just cut my losses and move on??
