<human>: I've been with my girlfriend four years now, however we did break up for a little while between April and August this year - but since we've been back together it's been really good - communicating every issue and being reasonable with each other over everything as well as generally having a good time and a good sex life.

However I've noticed recently she's started being incredibly protective over her phone and giving dumb excuses as to why I can't use it. It all seemed very textbook. 

I regrettably did the stupid thing of looking at her text messages when she left the room because it did all seem a bit weird and out of character for her. There was nothing necessarily incriminating but she had been talking to one of the guys she plans on moving in with (we're currently at different universities in the UK, and she's moving into a house of eight next year) it was all a bit friendly, bordering on flirtatious but I decided to think nothing of it. 

Fast forward to today and I decided to see if anything else had happened - looked at her messages and the text was gone. Is she trying to hide the conversation or did she just decide she didn't need it there anymore? I'm probably just going crazy as nothing else in the relationship is going wrong, but just wanted an outside source.

Can you provide a brief overview of the text?
<bot>: GF was acting weird with her phone - i checked, she was talking to a guy but nothing particularly sexual, checked again today and the conversation was gone. Is something fucked up?
