<human>: Before you jump to conclusions, hear the story.

For the longest time, my girlfriend had this app that basically lets you anonymously talk about people from the school you go to. It's basically a drama outlet.

A few months ago, someone started posting about her, saying "I really live X" "I am working up the nerve to tell X how I feel." "What should I do about my feelings towards X?"

Shortly after, my girlfriend anonymously replied "just tell her" because she wanted to know who it was (this person had been doing it for months.)

It made me very uncomfortable for obvious reasons. I asked her to delete the app, and she did. A week later, however, I found out she had redownloaded it behind my back, but she had a convincing story as to why.

She never downloaded it since. Eventually, she told me that her best friend (a girl) was the one behind it all just to  mess with her jokingly (though I could never confirm this story.)

Now she wants to get the app again. I don't want her to, and she is very upset.

I know, it seems stupid to not allow your S/O to have an app, but at this point, it became about principle to me. My S/O had me delete a bunch of girls she didn't like off my FB and went through my phone looking for apps that were linked to cheating (I didn't have any of them.)

So, to me, what's being vocalized here is "your feelings come before what I want" or even "this app is more important than you being uncomfortable about something." 

What's worse is she is very upset about it. Every time she leaves for work, she always says "I love you too" back to me, but today she didn't, and she huffed and puffed the entire time about it on the way out.

Am I wrong for being so upset over an app, or is she wrong for putting the app before my feelings?

Can you give me a shortened version of the text?
<bot>: My girlfriend has an app where you can anonymously gossip and flirt about other people you go to school with. Am I wrong for wanting her to delete the app because it makes me uncomfortable?
