<human>: Give me the gist of the text in a nutshell

Help, I was snooping on his computer today and I found a hidden folder with lot of bookmarks to porn of a rape and incest kind... I don't know if it's simulated, or real or what. I'm not uptight about porn, and we even watch it together... but this sort of crosses the line for me. I feel heartbroken over it because he *knows* I was sexually abused growing up, that it's a big part of my life that I'm still working on, and I cannot believe he'd be into this. I feel really bad for snooping and I just know if I brought it up he would make that the real issue, when the issue is how much this betrays me. We've been together for 1 year and he has been a perfect boyfriend otherwise but now I'm feeling like I never really knew him.
<bot>: Am I overreacting or is this a serious issue I should confront him about? I seriously thought he was the one and I've always worried something like this would happen like it does to all the perfect guys. sigh.
