Common interests outside of the home and family.
Partners who do things actively, that are not part of the relationship, help people bond deeper. Whether it is a simple hobby or a serious pursuit it will build both confidence and a feeling of being a team rather than you and them.
Becoming too much "best friends" hurts a relationship, especially in the area of sex.
Keeping a strong sex life is another thing that is often forgotten, x10 when there are children. Set apart time every day to connect at least a little. It doesn't have to be wild animal sex, although that won't hurt, but hug when you might just touch, kiss when you might just hug. When you do kiss make it a real kiss not just a peck. And that animal sex does have a place so make sure that it happens and that you aren't interrupted.
There is a time to stop answering the phone, unless it is an emergency. Tell your friends and family a code and make it very clear that if they abuse the code you won't answer the next time.
When you are out in public walking, hold hands, no matter how old you are. If you are the man you should be opening the doors and pulling the chairs. It isn't about her power to be independent it is about showing that she can depend on you to have her back.
Women; if a man opens the door for you, be it your partner or a stranger, its not because he thinks you can't do it.
Before you go to sleep every night take the time to hold each other, even if you have been fighting.
Finally; sex isn't a card to be played to your advantage. Play that game and your partner will find another dealer who doesn't hold the aces over their head.
