Married couples: What is the quality you value most in your partner?

He is a faithful husband. We fight and argue about a lot of things due to our differences, but at the end of the day, what I appreciate most about him is that I know his heart belongs to our family, to me. He doesn't go out with any friends, no vices, he can live without a mobile phone as long as he is with us. The only time he uses the mobile phone is when we need to go out and he has to wait at the parking or somewhere else for communication purposes. No signs of infedelity for the last 4 years, and hopefully he stays that way.
