I think that men think they need their man caves. They don't really do. They think they want them, and then the second they do get them and they have alone time and time away from the girl, and the girl is really cool with giving them alone time, then that's when they, or at least I, start to think, "So, why are you so cool with me being alone? What's wrong with me that you don't want to be with me every second."
