My girlfriend and I went out this weekend. She got really drunk and ended up getting kicked out of the bar for being aggressive. She claims the bouncer who removed groaped her. When she told me what happened I was upset tried to speak to the security supervisor and cursed him out. My girlfriend became aggressive with me, we argued and she pushed me and scratched me. I left with my best friend and when i got home my girlfriend was there waiting for me still upset. The next day we smoothed things over and I made it clear that her drinking and becoming aggressive was not okay with me. We had a relatively good day but we both felt somewhat distant and as if things werent quite back to normal. 

I should mention that her coworker who i have concerns about was also at the bar with her girlfriend and friends but left early. By concerns I mean I think the coworker likes her and often vents about her unhappiness in her relationship to my girlfriend. I have told my girlfriend how the frienship bothers me and that at minimum I dont want her sharing anything about our personal business with this person. ( Because I do fear emotional cheating).  So the next day I asked my girlfriend if she had spoken to her coworker or told anyone about the mishap that occurred the night before and she said no that she was embarrased by it all and wanted to keep our business private. For some reason something didnt sit well with me and i decided to go through my girlfriends text messages on her ipad which is sync to her phone. Most of the messages between her and her coworker had been erased. Then new ones appeared where she told her co worker everything that had happened and accused me of being dissmissve of her being groaped by the security guard. I text my girl friend and called her a liar I have turned off my phone and not spoken to her since. Right now I feel betrayed and cant trust her. I honestly dont know what to do or what to say. I would rather someone be honest with me even if it hurts me than being lied to.
