If I was spending time with my daughter and I got called on the phone about an emergency at home in which my partner needed me, I would leave my daughter to be with my partner.

Your dichotomous logic is narrow-minded to the extreme.

My child is my world. My partner is my world. You can have as many worlds as there are moons and suns. Your insistence that one comes before the other is YOUR approach to life. It is not the approach of most mothers. Try asking more than three that are not in your inner circle.
