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

Backstory: 
I've been with this guy for two years, and I can't say the relationship has been perfect or easy, but it has certainly been worth it so far. I bought him a netbook about a year ago for his online classes. A few nights ago, he was out with friends and I wanted to watch a TV show on the netbook, so I was looking for it and happened upon some porn. I don't have any problem with porn, so that didn't bother me. But I became curious. So I snooped a bit, looking for the rest of his collection, mostly because I wondered what he liked. Instead, I found a folder titled Misc. In the folder were pictures of his ex-girlfriends and lovers, and pictures of a few chick acquaintances of mine and my roommate. The pictures weren't dirty, but a few were in bathing suits or slutty clothes. He seems to have taken them off Facebook with obvious intentions. I've confronted him about it, and he has admitted their purpose and what not. I just don't know where to go from here. I love him and I want to try to make it work if it seems logical, but I don't know what it means.
