Don't take her for granted!
Don't treat her like a maid or a prostitute or a nanny!
Treat her like an equal (not a child, pet or an inferior).
Listen to what she has to say!
Don't lie/cheat/hurt her
Don't be demanding and controlling (She is a human being who was born with right to be independent and free!!!)
Think of marriage as a partnership! Work together, help out, clean, do your laundry, make dinner sometimes (if you can cook). Real men (and women!) are mature and they don't let society's social/gender roles dictate or control their marriage
Be responsible and don't cause drama and grief! Women look for stability and a man that is A MAN AND CAN HANDLE HIS OWN
Show love and affection! Be romantic and sweet! Keep the love alive
You got to show her through actions along with words (actions are more important though!!!)
