Nothing. That’s a lie. I would be happy for her if it happened.
I would hope that she would get a chance to come visit. I would hope that she and her wife could come to my house and see the consequences of their marriage. They would be an invitation inside, a hug, an introduction to my wife, and the offer of a meal.
The world is not going to stop revolving. My first choice when I need prayer is still going to be her. The “moral fiber” of the country is not going to decline. The economy is not going to change because of her marriage.
Nothing would happen if Z got married…except that she would be married and some lady would be very lucky to be married to her…and a friend would be happy for her that she did.
