My husband's side chick sent me a wedding invitation

A wedding invitation came to my office today. Gold envelope. My full name in calligraphy. The groom is my husband. Of nine years. The date is the Saturday he told me he'll be in Port Harcourt for site inspection. Reception here in Lekki, burgundy and champagne gold. There's a price list for aso-ebi, family of the groom. I called the enquiries number and his MOTHER picked up. She said ah, so she finally sent it, and cut the call. It's in eleven days. I've paid for the aso-ebi. I don't know why.
