Need to start healthy patterns

Hi,

This is my first post. I've been reading the posts of others and have found them very helpful. My husband was recently diagnosed with ADHD and naturally we are having some difficulties. I'm having a hard time with his need to call ADHD a gift and not work on the impairments. He was diagnosed in November because he set up an appointment with a clinic. I suppose I should have known it was going to be difficult because he keeps telling counsellors and doctors I wanted to get him diagnosed and on medication. I did present the idea that he had ADHD to him and we talked about how medication is one of the treatments but he seems to have rewritten our conversations. I hear that is a part of ADHD which is also hard for me to keep taking because I know he actually believes things I've never said. 

Is there any way to help our conversations be truthful? Is this something an ADHD counsellor can address? He's a very convincing talker with others and most people, except for his family, believe him. Will an ADHD counsellor catch on?
