The couple, who have been together for over a decade, first started dating in 2013.

In a 2018 Instagram tribute for his birthday, Ryan thanked Dun for "learning how to tie a bowtie for [their] first date".

Just before Christmas in 2018, the pair became engaged after five years of dating.

Ryan shared a series of photos to Instagram at the time documenting the moment.

"My dude asked me on a date. I said yeah because I always want to go on dates with him. Then he asked me to be his dude forever," she wrote in the caption.

"He's my heart outside my body. He's a cold water awakening and a warm bed; he's the place I can rest. Dudes for life. It was a really good date," she concluded the heartfelt post.
