My Fiancé calls me his girlfriend when he talks to people about me

Do i have a right to be upset? So last night my Fiancé came home from work and he was talking about a conversation he had with a co-worker and said oh my girlfriend does that. I told him girlfriend? We've been engaged for almost a year. And he was like I also forget to call you my fiance. Then again he was saying a conversation he had and again called me his girlfriend. I'm very upset. We have been having a rocky relationship and broke up 4 months ago for a week. Got back together he proposed again and we've decided to get married next year if we fix our issues. Is this normal? I've always called him my fiancé. Is it normal for guys not to call you his fiancee

Thank you guys! I apologized to him for getting mad about it
