Maybe he's just technologically advanced.....I was curious about the growing up statement because it can mean several different things. Is it staying out and partying until 4am several days a week? Is it not being on a solid career path, or is it just a matter of different interests? Maybe he likes to play video games and she like to visit museums. Who knows? To your point though, after 5 plus years and not taking the next step, maybe subconsciously his heart wasn't in it.
