"Yes yes yes, thank you for asking. Italy was one memorable trip. I sincerely thank you for all of your love and messages, means so much," Jaclyn captioned a series of photos of the couple from their Italian getaway.
"Im more emotional in a good way these days. I have always just wanted to feel this loved by someone. You were worth the 30 now 31 ;) years to find it."
In the first photo of the slideshow, Jaclyn showed off her diamond engagement ring on her left hand as she was embracing her future husband.
Many of Jaclyn's friends and former co-stars from Married at First Sight congratulated the former reality TV star on her engagement, including Dr. Jessica Griffin, who served as one of the matchmaking experts on her season.
Jaclyn first posted a photo with Dane on Instagram in November 2018, but she didn't announce whether they were actually dating -- although she dropped hints by writing how he's "adorable" and she's "lucky" to have him in her life.
Jaclyn and Ryan both appeared very committed to their marriage and the experiment when they starred on Married at First Sight, but Ryan refused to give up time with his guy friends and nights of partying while Jaclyn hoped to travel and live a gypsy-type of life when Ryan desired putting down local roots.
