Schedule some alone time.
Wait until after dinner to turn on the TV. Eating dinner at the table will almost force you to talk more rather than jsut eating while watching TV.
Have all your important conversations face to face.
Never pass up the chance to cuddle.
Spend a minute looking at each other before bed. Try to take a moment to face each other and look into your partners eyes... REALLY look. It's amazing how much closer this little exercise can make you feel.
