Relationships

My parents were always happily married when I was growing up. Nothing could stand in the way of them. But since they’ve become empty nesters after my youngest brother moved out, things soured between them. The other day they announced to me and my siblings they want to divorce. They sleep in separate bedrooms now and are only roommates at this time, and they are already shopping for separate apartments. I don’t want this to happen. I want them to love each other again like they did when I lived with them. My wife is pregnant with our first child, and I want them to be together as grandparents to my children. I want them to grow old together. Would it be a good idea for me to try to convince them not to divorce and to stay together and work things out? Or is it better for me to stay out of their business and not interfere?

What is the Jewish point-of-view regarding friendships with gentiles (not for the purpose of marriage)? Is it better be friends with a Jew who has little in common to make a friendship successful, or with a non-Jew who has a lot in common and with whom one feels close? In general, should Jewish status be a determining factor in who one decides to give priority to being friendly with? Or can one feel free to pick their friends based on who has the most in common, regardless of religion?
