. Serious talk isn't boring for most people, intelligent people I mean . And most intelligent people with inquisitive minds do talk about serious things with their significant others, family or friends. What do you think people talk about to each other? Of course if you bring these topics up with intent to demonstrate that you know more than others or in order to argue , then no one will find it attractive, but I don't see why you think serious talk is boring. Unless maybe in bed lol

Low self esteem could be addressed in therapy.
