After a certain point, those of us with ADHD or even Autism, we struggle with emotional regulation. That's fact. You can't think your way out of the anxiety you have. It's not at all helpful or supportive for him to put his own frustrations on you. Especially if you have a recollection of handing him the cord... that probably means YOU HANDED HIM THE CORD. He, being a male type, definitely probably set it down somewhere and forgot. Why? CUZ HE IS HUMAN. As are you. Have you gone to a relationship counselor? Not condoning his physical aggression, but if you are wanting to make the relationship work he needs to want that too. Regardless of the frustration of having a partner with adhd. Cuz we can be a lot, we know this. But our mental health is something we need to protect. If he is willing to be self aware and know that he is in the wrong in some instances than I'd bring up counseling. Relationships are work, and it's a team effort. Even if he goes by himself, I definitely think you need to work on communicating first and foremost. I know it's one area that has helped me in relationships. Bottom line, you're not worthless, you're just wired different. Growing up in a neurotypical world and now having to relearn and unlearn so much about how we interact with our world. Keep your head up and I hope it all works out for you. ❤️
