How would you feel if your girlfriend was texting with a guy at her work everyday?

My girlfriend works at the restaurant for few months already, and she keeps texting this guy at work everyday. I talked to her about how it is uncomfortable for me to know that she has been texting to this guy, however, we all end up being mad at each other. I do not want to make my girlfriends feel sad, or feel that I control her life. I don't know what am I suppose to do anymore?
