“I don’t even know if he is right to directly connect his stuttering to my own struggles.” I would say that it doesn’t matter too much. If you are having anger issues that are causing you to lash out at your partner, that’s not just your own struggle any more. Regardless of whether it’s correct or fair for him to link your anger to his stuttering (and I do think that if your anger is stressing him out it could have an impact), there really is no excuse for lashing out at a partner. I don’t know the details here but I do think it’s important for you to work on communicating better when angry or upset. My husband stutters, and learning how to argue/have a conflict with a partner who stutters is important, because you could very easily totally bulldoze them. Thankfully we don’t have much conflict but when we do we just have to wait until we’re both feeling calmer and then I make sure when we’re discussing it that I give him as much time as he needs to say his side.
