What would you do??

I feel lost about my relationship. These past three days we've been arguing. We argued mainly about the fact he doesn't listen to me and I have to repeat things every single time.He has ADD and yes I know that means he has a short attention span but it gets annoying and exhausting to have to be doing this constantly. I personally think it's low key selective hearing because topics that are interesting to him he's all into but when it's not he's like huh.. What did you say😑 or saying things I did not say at all. It also blows me that a lot of common sense things people know he doesn't know... Idk what to do but it's just making me not wanna deal with this.
