brother

My brother is engaged and set to be married in June. My mom keeps telling me how he is already wearing his wedding ring, and refers to himself as a husband. He lives with her, who we all love.
They had business cards made up with his last name - D & A Smith. They bought a business together last month.
I keep thinking that they secretly eloped and aren't telling people. I messaged him about it jokingly and got no response. hmmm
