As a husband, is it good to tell your wife everything you want to do ?
It actually depends. There are some questions a man needs to consider. Who is my wife? Is she a builder or a breaker? Is my wife trustworthy? How has her contribution ( I mean advice wise) been so far? Reflecting on this questions will help a man go far in deciding whether to or not tell her wife everything he wants to do.
Yes, is very important that you tell her, (if) only the trust is there
To my own point of view, is not everything you want to do you tells your wife, at least man up to handle things on your own
