As a person who has both ADHD and a stutter, I can sympathize with your frustration and your husband's pain. Communicating with a person who stutters requires patience which you clearly lack. His stutter does sound rather severe, from the way you describe it, and coupled with your own struggles with emotional regulation, your reactions towards each other creates a feedback loop of further frustration. As others have said, this may not be the right sub for advice. This isn't the place to vent at people who share your husband's disability. I think if you'd lead with the work arounds you and your husband have tried (and cut out your negative internal feelings) then your post might've been better received.  Using written communication in tense situations is a good idea. If your husband's comfortable with this, you could also invest in a text-to-speech app or dedicated device for more efficient communication.  I sincerely hope you two can find a mutually beneficial compromise and attend couple's therapy to help manage your competing struggles and needs.
