Am I the only one 😞🤔

Me and my SO have been together for 6 years... and I’m still not engaged.. and so when I talk to people I don’t know for important things I always just call him my fiancé because I feel like we don’t get taken seriously when I just call him my boyfriend. It’s upsetting because I just want to actually mean it when I call him that.. I mean after this long why haven’t I seen one?
