Divorce. I Don't Want to Lose Her

At 12 a.m., I hear my mobile vibrating and immediately grab it. Reading what appears on the screen from my husband:
Incoming message from “My beloved”:
Happy New Year, dear—me and our daughter.
I miss you, and soon I’ll be near.
Love you, baby)

We don’t have a daughter! What is he talking about?

We don’t have a daughter. He clearly has one.
That’s how my New Year began. The year of ruin and the fall of the family.
