Does people fill in words for you?

Does people fill in words for you? My husband has very little patience for my speech when out talking to others. At home he lets me stutter, but out and about he fills in words for me and I want to punch him. I’m trying to appreciate that he wants to “protect” me and reduce my anxiety, but I’m grown and if I stutter, the other person will just have to deal with it. I need to tell him but I just haven’t for fear of needing the help and him never offering again 😭 especially if there came a time I “needed” his assistance.
