He had a huge heart, always.” “I can’t explain what it’s like to lose a sibling,” she continued. “Someone who’s been there from the beginning and shares the same memories. No matter what we were going through, I loved him immensely. Life as I know it will never be the same.” Alongside the sweet tribute, Melissa included several photos of herself and Ryan through the years, including a throwback picture of her holding him as a baby.

The businessman—then 29 years old—was paired with receptionist Jessica Castro and the two married after meeting for the very first time at the altar. Ryan De Nino/InstagramThe pair decided to stay married on the Decision Day episode of the series, with Jessica explaining at the time that she was not interested in getting a divorce. "I come from a family of long successful marriages," she said on the show. "The word 'divorce' just doesn't fall into my lifestyle." But by the reunion episode, their relationship had hit the rocks, with Jessica accusing Ryan of cheating on Valentine’s Day. “A week prior to that, we had a blow-up because he told me that he was gonna be busy. So, I didn’t see him,” she said during the reunion episode. "A few weeks later, I find a Valentine's Day card from another female at his apartment." At the time, Ryan denied the accusation, arguing that he “can't control people from sending me cards.” The couple divorced after their season ended.For the latest breaking news updates, click here to download the E!
