The emotional thing is a strain of ADHD. I’m pretty much that guy. Except, you know , far more dashing and with a hypnotic charm, lol. (Cough) where was I? If his emotions express themselves in a positive way — that bit is key — and you enjoy a guy who’s emotional, you may have a guy who could make you happy. But make sure the emotions are positive. There will be a lot of them. Do they cause him trouble at work? Does he get into fights? Has he hurt anyone? Is the tone upbeat and pleasant on average? Is he a happy emotional guy? That’s key. Most guys can’t re-start the hyperfocus on purpose but that emotional thing? That’s probably on 24/7 and might be something you find rewarding.
