<human>: Can you provide a brief overview of the text?

So, here's a bit of information about me, and a bit of background to my story.
I am a female, and I am bisexual. I have a girlfriend whom I've been dating for a few months. She absolutely loves Coca-Cola. And she's also very jealous of my female friends.
So today I had went out with two of my female friends and we went shopping. I asked my girlfriend if she wanted to go with us, but she said no, she wasn't feeling well. I felt bad, so I decided that I'd pick her up a soda and bring it to her on my way home. Me and my friends went out for a few hours, went to a few stores, and just had fun. I was on my way home at about two in the afternoon, and I stopped at a gas station to pick up a coke for my girlfriend. Now, as you may know, the Coca-Cola company has been putting labels on coke bottles with random people's names. Without thinking, I grabbed a bottle with the name James on it. I paid for it and headed to my girlfriend's house. I got there, knocked on the door, and she let me in. We sat inside and talked for a bit, then I gave her the soda. She took one look at the bottle, then asked me who the Fuck James was. I didn't think she was serious, so I messed around with her and told her he was just some guy I sucked off at the gas station. That's where I fucked up big time. She started freaking out, calling me names, and even slapped me a few times. At the end out the day, I ended up at home with a black eye and single.
<bot>: Bought my now ex-girlfriend a soda with some guy's name on it, she went bat-shit crazy, and now I'm single and bruised in the face.
