Input: My girlfriend has this friend who is staying with us. She's been at ours for roughly a month and we have a spare room, so it's not that big of a deal. She works often and studies but she's staying with us to avoid an ex. 

My GF and I left for the weekend to my moms and the friend was going to be alone at ours all weekend. Now the girls have been friends for years and we're roommates before so it shouldn't have been a big deal, but I didn't want her to be sneaking around our shit while we were away. So I set a little 'boobie trap' which was an iron board leaning up against the door so that if she did open it, it would hit whomever decided to snoop up in our room. 

There is absolutely no reason this person should have been in the room. None. But alas she did and admitted to it.  I instantly shook my head and said she shouldn't have been in there. She claims she was just looking for something innocuous and then started crying and blah blah blah. I clearly don't like her, but AITA in this sitch?

calling out gf's friend for going in our room whilst away
