The former U.S. Army veteran proposed to Boyd on live television while competing on reality TV show Dancing with the Stars in May (15), but the two have now decided to part ways.

"After long and careful consideration we've decided to end our engagement," Galloway wrote on Instagram.com. "We love each other deeply and we're confident we will remain friends. While we wanted to share this with you, we appreciate the respect of our privacy at this time."

"We can't thank you enough for all your unwavering love and support," Boyd added. "It has meant, and means, so much to us so we wanted to share this with you firsthand. This is a very difficult time and we appreciate y'all for respecting our privacy as we go through this."
