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

Me and my girlfriend have been dating for a month but we got to know each other for a month and a half before that. So far everything has been great, but something happened. A few days ago her computer broke and she needed one to do homework and study so I said she could borrow mine.

I gave it to her with the password and left her alone to get her work done. But when I came back she had gone through all my messages in iMessage and all my photos in iPhoto including the trash bin.

She found a conversation with one of my ex girlfriends that I had lied about, but the conversation showed that I had no interest in this girl anymore and that I just wanted to see how she was doing. But I understand why my girlfriend is mad about this. I lied when I should have just told the truth.

However, she is still angry at what she found in my photos. There were naked pictures from an ex girlfriend that I did not know still existed at all. I had purged my phone and computer of them, but she found them in the trash and the photo stream.
<bot>: My girlfriend went through my whole computer and found things that upset her but were from the past. Was she right to have done this/should I be mad at her for going through it behind my back?
