Alfredo is thinking about the mess he made on his love life upon hearing the conversation of Carmen and Don Julian about his relationship with Ezperanza.
He had accompanied Don Julian to judge Del Valle's residence. He met Julia Salas for the first time. He was embarrassed by the fact that he continued addressing her as Mrs. Del Valle.
Please accept my apologies for mistaking you as Mrs. Del Valle.
Oh, it's nothing, I've had a similar experience before.
It became more common to visit the judge's home. Then, despite being engaged to Ezperanza, He realized he was in love with Julia.
Julia was reunited with Alfredo following the procession honoring the Lady of Sorrows. When Julia found out about Alfredo's marriage, she gave him a congratulations.
Thankyou, Julia
Congratulation on your wedding

The wedding happened, thus, he chose not to break his word and avoid social humiliation.
