How does ADHD affect your marriage?

Or committed partnership/relationship?

My neurotypical husband and I keep having the same issues, 21 years in. I’m really tired of this repeating pattern. I feel rejected, he shuts down emotionally, I hyperfixate on relationship advice, things get better for a while, the cycle repeats. At this point, I’m just exhausted. (I also have a chronic illness, I must be really fun to be married to.)

I guess I’m trying to figure out how much of this is my rejection sensitivity dysphoria. I don’t know what a reasonable reaction is anymore. Any advice? Thanks, everyone.
