He still has her nudes...

I've been with my SO for 3 years and then some. And we were cleaning out the pictures on his laptop and he has all of his exs nudes. They dated for a little less than a year so I connected dots and knew they sent them. But I was kinda hurt that he still had them. So I asked him to get rid of them only because they made me feel uncomfortable being on his computer when they are still friends and talk regularly...he refused and actually got upset with me for being jealous. I am pissed but mostly sad. Like what is so important about her nudes hat we had to fight over you deleting them... am I overreacting???
