Well, I had a big block once I wanted to say my adress in public and my wife was also there. The next time i was about to say my adress again she told me to "say firstly the adress to me". I said "why?". She said "because you did FFfFFffffFFFF the last time". ​ We didnt talk about my stutter much to that point and I felt extremely offended and was really upset and disappointed. But later I explained her how I felt and she understood and apologize. Now everything is great, I explained her how to react and she even told me then she can talk for me if I think I´d stutter (she is so nice that she does big part of the public communiation for me) :). ​ So yeah, just talk to her. Do it. "Dont hesitate!" :)
