There's this guy I work with four times a week. We've grown pretty close. We both flirt and talk a lot, over all we have the best time at work. Recently he's been acting differently towards me and shifting his attention to my friend who is also one of our co-workers and it's driving me up a wall. He treats her how he used to treat me and now it feels like he hardly talks to me. I want to tell him that I like him but I don't know how the out come is going to be. Seeing how he was with her the last time we worked together killed me on the inside.
