I thought this quote was appropriate. I found it on a blog I look at often.
"Most people get married believing a myth- that marriage is a beautiful box full of all the things they have longed for: companionship, friendship, intimacy. The truth is that marriage, at the start is an empty box. You must put something in before you can take anything out.
A couple must learn the art and form the habit of giving, loving, serving, praising- keeping the box full. If you take out more than you put in, the box will empty."
