Am I cheating?

Jesse

Hi there I'm a guy and I'm at university. My girlfriend is one year older and lives 50 minutes away from me and is still at high school. She is incredibly insecure about me and is scared that I am seeing other girls at uni. She gets incredibly upset whenever I even mention another girls name. I am not allowed any 'girlfriends' because of this, and I am not allowed to drink in the weekends without her getting upset. I have never cheated on her in any way at all I might also mention. However a few months ago my girlfriend and I had a huge fight (worst we've ever had) and I asked another girl to come over and watch a movie with me over Facebook so I could talk to her about my girlfriend and maybe get some advice on what I could do to make things right again. My girlfriend told me today that I was logged into my Facebook on her laptop which is weird because I've never even been on Facebook on her laptop before and that she read all my text messages. She hit me up about it and told me that asking to watch a movie with another girl is basically cheating and she also think that I fucked her too. She is incredibly angry, more than she's ever been before but do you think she is going over the top or am I just a cunt? Cheers.
