My Ex-wife Wants Me Back

My wife didn't want to have children, so we agreed to have sterilization surgery together. Little did I know, she regretted it after I had the surgery. She said, "I feel like two people should have a child together. Now that you've had the surgery, I'll have to find someone else like Nick, and when the child is born, we can raise it together." It turns out she had already made up her mind to have a child with someone else. So I smiled and said, "Okay." But as she wished, I asked for a divorce. Now she regrets it.
