<human>: A few days ago my girlfriend went to visit family in another state with her aunt and uncle, and I've been home alone holding down the fort and feeding cats. I was using her computer to download and print my resume off of drive. I went into the documents, and there was a file called "I still love you" in the folder created a couple weeks ago. 

Thinking it was about me I opened the file and read it. What she wrote wrote about was how she "still f**king loved her ex" from 1.5 years ago and missed how she held her, how guilty she felt (my gf cheated on her) and cant stop loving her. This made me feel kind of sick. I then texted (should have waited until she was home) and asked my girlfriend if she still loved her ex, and she replied that she loves her as a friend and misses being her friend. I told her about how I read the file and it seems like shes not over her. She said she doesn't recall writing it, and was probably depressed or drunk at the time. we then got into an argument about it, She was saying that note was personal and wasnt meant for me to read it and I was thinking too hard about it. 

She doesnt come back for another 2 days and I don't know if I can believe her on all of this, and have no one else to talk to about it. I tried calling her to talk about it more, all she would say is you just have to believe me, it was just a temporary thought doesn't know why she wrote it. I dont know what to think anymore, I'm going to sleep on it but also looking for advice.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Found file on GFs computer detailing her love for her ex. Asked her about it and claimed she doesnt remember why, claiming it was just a temporary thought that had no actual meaning. Halp
