I notice that several gentlemen have put forward articles on what you should be as a husband. So here is mine. Not all men agree with each other's codes. My suggestion is set your own ethos and set it with what you know. For example what I know is the British army ethos and as strange as it may sound it can fit to a Taken In Hand relationship as it does to my muckers.
British Army Ethos
Selfless Commitment: In a relationship it is not just you any more. Stick with your wife like a team. A team is only effective if all play their parts in full. Put her before your own needs, trust her totally; as the leader of the relationship remember she comes first and if you work hard for her she will be more willing to do things for you.
Courage: There are many different forms of courage and in a relationship you need moral courage, for if you make a foolish mistake or commit an error of judgement you have to have the courage to face your wife and admit you were wrong rather than take the coward's way out with pathetic justifications: her respect for you will plummit if you try that. Have the courage to do what is right rather than what is easy.
Discipline: We are all familiar with discipline in a taken in hand relationship but lets not forget self discipline which is what you need to put her before you. If she needs your help or emotional support then you have to give it her. Regardless of whether you are knackered or not in the mood she comes first. What right have you got to discipline her if you can't discipline yourself?
Integrity: No one likes a liar and she cannot trust you or rely on you to command her if you have no honesty: be open and honest or the relationship suffers.
Loyalty: If a woman gives herself to you she naturally would expect absolute loyalty. That means not betraying her trust, and sticking by her side even if the going gets tough. If she has done something foolish or gone off somewhere that you don't know focus on sorting things out or finding her and do not show her up in public and make a fool of her. If necessary, spank her later behind closed doors.
Respect for others: respect her position in life and her expertise in what she is familiar with even if it does not seem very impressive compared to what you do: for example if your job is important and she is a housewife repect her for that because would you want to be in her place? You gain her respect by earning it not by putting her down.
This is what I would put forward as a husband's ethos as it's what I'm familiar with. I don't expect anyone to agree with it and I'm sure many other men and women have their own codes and values to live by that fit with what they do.
