Please explain to me: Why does he sound like a teenager?
I have been dating a 45-year old man with undiagnosed ADHD for a year. Both me and him are convinced that he has the condition. One of the many things that puzzles me about his behaviour is this: He mostly acts and speaks in a way that is relevant for his age - that is in a responsible, mature and experienced way. But suddenly he reacts, jokes and makes comments that is really embarrasing, like some teenager. To be frank, he sounds stupid and I really get turned of, I am in my forties and don't want to date a kid.
