As a husband, is it good to tell your wife everything you want to do ?

The answer is both yes and no. Depending on the situation, what exactly you want to do, the temperament of your wife and precious experience of how she reacted to what you told her in the past. It is very good to be open to your wife in all matters because it would build trust in the relationship, but where she is not supportive to good plans eg wanting you to spend up money you planned investing, in this case one may keep such investment plans away from her because when you’re no longer able to keep up financially you would still be the one to be blamed.
