I picked up my boyfriend from work so we could get something to eat. On the way there, he suddenly said "lets go to Mcdonalds". We pulled in and I ordered my food, I told him that he should order too and I'd pay for it as a treat. He ordered his food and I paid. I got a cup with my meal so I went to fill it up with some soda. As I was walking to fill it up I saw him ordering something else. After I filled up the cup, I walked over to him and asked who the extra meal was for. He said it was for a male co-worker and I caught on that something was wrong. I said that if it was for a female co-worker, it was fine to tell me. He then said some other things and then I opened the bag and took a smell of the food to prep my pallot. His face suddenly went through a mix of emotions, the last of them being angry.

He suddenly started ranting about "what if it was for a girl" and then proceeded to throw out the food he bought for the other girl and his food. He said he had lied about who it was for so I would not get mad. I replied that I was mad because he lied about who it was for, I didn't care who it was for Male or female, just the fact he lied.

I don't know how, but he started talking about this girl and knew her nationalty, age, which combo she buys at fast food places, her college major, her salary, where she lives, who she lives with, who sleeps at her house, etc. To make things even more odd, she lives right near work, so it would be easy for them to get "jiggy" at her place.

What makes it feel even worse is that I am an avid web surfer and TV show watcher who knows the signs of cheating and all the other stuff pretty well.

We have had a few fights lately and we have brought her up. He said that she is in the back of the office/work and that he is in the front of office/work so they don't have a chance to talk, yet he knows so much about her.

What's the verdict on my boyfriend?
