How does your partner react when you disagree with him or her?

Does your partner 1) acknowledge the disagreement and that you might be correct; 2) tell you you're wrong; 3) attack you; or 4) some combination? If your partner does or might have ADHD, do you think the reaction has something to do with ADHD or do you think it's a separate aspect of his or her personality? I'm assertive and I like to be right but I'm also willing to acknowledge when I'm wrong. Former partner is not very assertive, likes to be right, and has become more willing to acknowledge when he is wrong.
