#6: Never ward her ideas off!
In certain stages of life, your wife will bring new perspectives and ideas to the table. While they may not always be matching yours, do listen.
Listening to your wife and paying attention to her ideas and suggestions is probably the most important thing you’d be doing in order to grow your relationship. Accept her ideologies and theories; if you can’t, disagree respectfully. Never be petty and always keep your ears peeled for ideas and advice. Who knows, she may be making more sense than you!
