Would you be upset if your bf kept talking about another girl?

My bf has been talking about his coworker lately. And he even mentioned how there is is nothing to not like about her. He keeps being her up. And it kinda bums me out because he talks about her more than any of his other coworkers. I am trying to brush it off. But it got to me today when he was talking about her. And could only mention how I had a pimple on my eyelid, and how my eyeliner was uneven. Like come on... that really didn't make me feel special at all
