One of my guy friends recently started seeing someone. I'm happy for him, but at the same time I'm really not liking it because we all work together. I'm in the process of training his girlfriend in a particular section at work, and he kept coming over either talking to her or putting me down in front of her by bragging about how much better he does the job (that I also trained him at, mind you) or teasing me. Even at the end of the day when I was showing her how to set up for the next day, he kept hanging around impatiently waiting. It was extremely distracting. Basically he was being a jerk today probably to try to impress his gf. He's never been this cocky towards me before. It was hard to bite my tongue, but if it doesn't stop I think I might actually go to my boss about it. I just don't want to start an argument or eff up a friendship.
Why tf do co-workers date anyway? I'm totally against that.
