My husband pokes fun at me about my ADHD, but so do I. It's not a problem with us at all. He truly does understand (or tries to understand) what I go through. Our relationship has been very close and full of humor. I was diagnosed while I was struggling with nursing school (age 34). I had to repeat a couple semesters, so we joke that I took the scenic route. My suggestion is to talk to your wife during a time when the two of you are not at odds and let her know how you feel and try to explain to her how it bothers you. Also, learn to laugh at yourselves, that is what has helped us get through things. We have a joke in our house that I gave my dog ADHD because she's a little "out there" sometimes. If his teasing bothers me, I just let him know and he stops and will apologize. I hope things improve for you.
