In 2009, Perez met and later married Arturo Oteras.
Oteras was called as a defense witness on Monday.
He testified that he loved Perez, and that she had told him how Jacquelyn died in her arms.
As photographs of the couple's wedding were displayed by a projector, Perez showed the most emotion she had during the day, as she cried while she watched her husband weep.
"I will stay married to her," Oteras said.
The couple have a 21-month-old baby girl together.
