It is common for misunderstandings, frustrations, and resentments to build up in relationships where one or both members of the couple have ADHD. This is the most likely when the symptoms of ADHD have never been properly diagnosed or treated. The upside is that building a healthier and happier partnership can always be worked on if turning these problems around is a priority. The more you learn about ADHD and the role it plays in your relationship, you can create more positive and productive ways to respond to challenges and communicate better.
