AITJ for telling my brother he can't bring his new girlfriend to my wedding?

¿Soy el malo por decirle a mi hermano que no puede traer a su nueva novia a mi boda?

OP's brother started dating someone two weeks before the wedding and wants to bring her. OP says no — the place cards are printed, the table is full, and the guest list was closed months ago. Now his brother says he might not come at all.

Hola. Tengo 29 años y me caso en dos semanas con mi novia Emilia. Llevamos cinco años juntos y este día es muy importante para nosotros.
