I have a very loving, caring, and special marriage to my non-ADHD wife. That said, we have ups and downs from time to time like anyone else. One of the "downs" comes from the ability that us ADHD people have to make our partner feel like they are an afterthought.
I have been blessed with a passion for art, music and technology. However, for most of my childhood and adult life this "blessing" has been a horribly painful mountain of burden. The never-ending chatter of thoughts, ideas, melodies, etc. would be maddening and result in failed attempts to execute; time after time and year after year.
A few years ago I started treating my ADHD. Now, with the ability to execute; all those interests have transformed into pipes that allow me to find endless ways to empty/alleviate that "chatter" that used to torment me.
I am so much happier and learned how to function day to day in ways I never thought possible. This has had allowed me to focus on my wife better in the moments when I have cleared out the chatter. However, treatment has not changed how much time goes into managing all the noise. It has just made it not hurt me like it used to. I am not "available" any more often, just more "present" when I am.
So, one of the catches is that now all the time I spend emptying my brain comes off as enjoyable (and many times I am having fun). Regardless, it is still being done out of necessity. I find that actually can have a negative affect on your partner because now you aren't simply "not present" because you are lost in your brain chatter; you are "not present" because you seem to spend much of your time with things you love more than them.
I know that not all of us ADHD people have the same interests and available outlets for our chatter. For those of you that have an ADHD spouse that sounds a bit like me; when they find outlets like I have, try to not mistake the time, energy, and joy they put into popping their daily brain blister as a something to compete with.
Even on days/weeks when I seem to spend 90% of my waking hours focused on other things, I am ALWAYS 100% in love with my wife.
I share this for NON-ADHD spouses to maybe better understand why we spend so much time "elsewhere". However, I want to stress to my fellow ADHD people, when you are lucky enough to have a partner who reads things like this and it helps them understand you better; we have to remember that their "understanding" does not equal fulfillment. We need to continually look for better ways provide more time and communication with people we love.
