Arquette's Marriage Advice: Be Kinder

Hollywood couple David Arquette and Courteney Cox Arquette prove that opposites do attract -- and David dished to "Extra" on how therapy helped their marriage.

"Courteney and I were going through a time and the therapist had great advice," David admitted. "He said, 'Listen, what you guys really have to do is be kinder to each other.' It's such a simple concept but it's a really important concept with a relationship."

Arquette added, "The other great advice he had given us was when you're in a relationship; it's really not just about you anymore. You have to consider another person's feelings and...how certain situations will affect them and with a child as well... It's hard in this town especially, just in general relationships are, but they're great."

David declared, "People throw away relationships too easily -- marriages especially in this town... not only in this town, but in this world."

The actor also opened up on how becoming a father to daughter Coco changed his life. "What amazed me about having a kid was it redefined my definition of love... It just makes you love your partner so much more, makes you love life more and this new person unconditionally. It's so cool," he said.
