YES thats exactly what it means. You talk to yur wife so that yur house can function normally and you raise the kids. Theres no heter for frivilus talk like good morning or talking about books or anything else thats not important.
Depends on what it is. If its important like choosing a yeshiva for the kids or arranging a doctor appointment or discussing what food is for shabbos then yes. but not to stam shmooze.
If you want to run your marriage that way, go ahead. But as for me, I will talk to my wife as I please, not based on what you say. And if you want to believe that I am a sinner for wanting to talk to my wife about anything other than what is absolutely necessary, then I will wear that tag with pride.
