He is clearly upset that people are talking smack about him for allegedly cheating with the cocktail waitress.
David says that he and Cox are the best of friends, but that’s all there relationship was…a friendship.
"We're not having sex, and I completely understand," Arquette said when touching on the point that they haven’t had sex in 4 months. "She's in a place of wanting to be real and emotional. She's an emotional being. She's an amazing woman. If it doesn't feel right, she doesn't feel like bonding in that way."
He also touched on his immaturity being a problem for Cox.
"She says that to me: 'I don't wanna be your mother anymore,' " Arquette said. "I appreciated that. I respected that. I've been going to therapy. I'm trying to grow up."
David also got very emotional during the phone call calling Cox his “best friend," and added: "She's the greatest woman I've ever met … Now, yes, she's got her issues. She tries to take on everybody's problem. She tries to be the mother to everyone – that's why she doesn't want to be the mother to me anymore."
"The reason for this separation is to better understand ourselves and the qualities we need in a partner and for our marriage," they said.
It’s sad when people fall out of love, but sometimes there’s just nothing you can do about it. When the spark is gone, it’s gone!
