Richard, Tina, Julena and Rebecca all say they feel responsible for how their relationships are managed. "We take care of each other's needs, it's not him taking care of us," Julena says. "We're taking care of each other, the four of us."

"Sometimes one of us can give somebody else a different perspective. It's almost like a counselor," Rebecca says. "You have two counselors there all the time, but someone who truly knows what you're facing, what the situation is every day."
