A guy that I work with started talking to me and flirting with me. We became close friends. We traded cell numbers and are friends on Facebook. After a while he stops flirting and hardly talks to me. I confronted him on it and he told me he was sorry and that he hoped that I would still be his friend. Why did he just back off all of a sudden. I mean we still talk but not as much. He seems to be around other friends all the time. I don't know what to do. I like him a lot but since he started acting like that I will not tell him how I feel. Please somebody help me!
