Do y'all's partners regularly repeat what you JUST said as if you didn't just say it?

I am Dx and my partner is not, and doesn't want to be.

I realize now this behavior may be due to inattentional deafness.

For some reason, this irritates me the most. If your partner does this, how do you deal with it? Do you just let it go? I have brought it up, but obviously that isn't going to change how they're able to listen.
