"To put it very frank, after the show, we realized we weren't communicating as well as we once did," Colton said, adding, "It was a very real and very emotional breakup, but it was also very good to be real and emotional because it forced us to have conversations and move on.

As for why the two never took the next step and decide to tie the knot, Cassie, 25, told E! News last year that they were simply "taking things day by day."

"We're not putting pressure on ourselves," she assured. "Overall, me and Colton are in a very normal and real relationship. And while it's difficult and it has its challenges being in the public, and like every relationship it isn't perfect, but we do love each other and we're on the same page. And we're very happy."
