<human>: Can you give me the gist of the text in a nutshell?

Long time lurker, having a small thing that I would love advice on.

GF and I have been together for over a year. She is pretty incredible, everything I want, yadda yadda. Our relationship is great. Recently something that happened quite a while ago has been bothering me a little bit that I had pushed to the back of my mind.

So back about 6 months ago, I jumped onto her laptop to do something (normal) and when she closed the chrome page she had open, a downloaded picture of a guy was there. She deleted it super fast like she didnt want me to see it and mumbled something about not knowing how that got there. Now I know this guy, he goes to our college and him and I are somewhat friends, say hi to each other what not. Not very close. Well her sorority and his frat were partners for a weekend thing and they had met and became friends right before this happened. And we had been in a big fight the weekend before and barely spoke. What weirded me out was that this picture appeared to be downloaded from FB or something, which is really odd. I had I suppose pushed it out of my mind at the time and it just came back to me over break.

I feel like I'm being a bit crazy here by letting this bother me, but I can't find a way to justify why it was there. And why she was secretive about it. I have a tendency to be pretty protective and jealous, and this is just bugging me and I can't shake a bad feeling. Even though I don't think anything would have happened as my GF appears to be extremely faithful.

I am thinking of just casually bringing it up next time we are together to gauge her response. I think if she had an explanation that made sense I would feel a lot better.

Is bringing it up the right thing to do?
<bot>: GF has a pic of a friend on her laptop, it was downloaded. Weirded me out and now bugging me months later.
