I'm glad you two can get along in this capacity. I have ADHD and I'm very much like your wife and my last partner was like you, but my ability/tendency to multitask tended to be overwhelming for her even when it was just me doing it. Like, if I tried to talk to her while simultaneously listening to a podcast and doing something on my phone, she would be feel overwhelmed by association and ask me to stop the other things and just talk to her.
I don't think she had ADHD though so maybe it was different for her and more of a sensory thing. I just appreciate that you two are so different (in this aspect) and still able to respect and adapt to each other's differences.
Your conversation quality might be noticeably different when you are doing something else and when you are not (even if you don't notice it).
For me, I can kinda participate in a dialog when distracted, but I'm definitely not pulling my weight in such cases, so the person on the other end has to do all the work.
