I have been in a 25 year marriage with undiagnosed ADHD and 3 years where the diagnosis was known. I unfortunately was diagnosed with a rare, serious disease a few years ago. I won’t list all of the problems and issues as it is a very long list. I will simply say – move on, and look elsewhere for a partner in life where there is no ADHD. Life in a partnership with ADHD might be liveable when you are strong yourself, but when you need support due to a health crisis or other serious issue – you realize your partnership is a very lonely place.
