The relationship between Artie Goldstein and his daughter, Jill, has always been a “special” one, but when his daughter told him she was marrying a woman, it became difficult.

In a new ad for online travel agency Expedia, Goldstein shares his emotional story of flying across the country to attend his daughter's wedding. The three-minute video shows his journey that tests his feelings, challenges his beliefs, and, in the end, changes him for good.

Goldstein, a retired businessman, said he was surprised when his daughter’s fiance, Nicki, asked him to marry Jill. He had imagined his daughter growing old with a man in a traditional marriage.

“I didn’t say yes, I didn’t say no,” confessed Goldstein. “Coming out to the wedding from back east, I had real apprehensions about it. What’s this going to look like? Two girls getting married.”

Goldstein realized that he had to make a decision: to maintain a healthy and happy relationship with his daughter or lose her.

“This was a situation I had to come to understand,” he said in the ad, which uses footage from the actual wedding. When he arrived and realized how happy his daughter looked, he accepted her new life.

“All that trepidation just sank away,” he said. “That was a big turning point.”
