Yes or No Answers

Ok.. I've got something I need some help and feedback on. My husband and I have been married 11 years, together for 13. We only learned about a year ago he's got ADHD, and he's medicated now.

I seem to be unable to answer a Yes or No question with Yes or No. I start to analyze the question and justify my answer before giving the Yes or No answer. This is something he's complained about almost since the beginning of our relationship. I'm in therapy also, and my psychiatrist likens my condition to PTSD, after so many years of dealing with my husband's lack of impulse control. I believe that may be why I do this, but I'm not sure - is this just a female thing?
