Marriage Scammer Asking for Exorbitant Betrothal Gifts

On Mother's Day, I asked the delivery boy to give a surprise to my long-distance girlfriend. The delivery boy accepted the red envelope and said politely: "Brother, you are so romantic. Even though your child is so old, you are still so attentive to your sister-in-law." I was stunned when I saw the news. My girlfriend and I have only met twice, and we haven't even gotten married yet. How can we have children?
