An excellent wife is the crown of her husband, but she who brings shame is like rottenness in his bones.
Know who you are as yourself and be confident in that knowledge. In other words, you can't love someone else unless you love yourself first.
When learning how to be a better wife there are some things to keep in mind. Treat your husband exactly how you would like to be treated. Do not take him for granted but don't be a doormat either. There should be an equal division of labor to keep things in order. Some things, like dishes or laundry, should be done together. Never presume that just because he's the guy he should be the one to take out the garbage or fix the leaky sink.
If things are not going as well as they should it is possible that the communication between you has broken down somewhat. In that case, try to pick up on whatever it is that may be bothering him. Listen to the things he says or, more importantly, the things he doesn't say.
Maybe he is feeling a little under appreciated, then all you have to do is pay more attention to him or let him have a little space. Tell him you want him to go have a night out with the guys. He will appreciate this and start to feel like his needs are important to you just like yours are to him and the relationship will once again be on an equal footing.
Take an interest in the things that are important to him, even if you don't get it. Sports, cars, whatever...try to be interested, at least for a while, ask a question or two and then you can safely go about your own business. Or, if you really are interested stay and learn all you can about what he is doing. You might find a hidden interest and he might like teaching you something new.
A good relationship is based on love, trust, and mutual respect. If you find you have trust issues the best way to overcome them is to talk to him and try to resolve them. If you get jealous every time he wants to go out with the guys, it is probably your baggage and not his.
Relationships do take some work to be successful but the issues, if any, should not be all-consuming. There has to be time for the fun stuff, too. Read and follow these tips on how to be a better wife and you will be appreciated more by him and not considered a doormat or a nag.
