Slain Colorado mom Shanann Watts said months before her death that she was lifted out of a trying period in her life by meeting her husband Chris — the man now accused of killing her and the couple’s two daughters.

“I believe that everything in life happens for a reason, and I also believe people are placed in our life for a reason,” Shanann said in a Facebook Live video approximately four months ago, before she and daughters Bella, 4, and Celeste, 3, were found dead last week.

On Monday prosecutors formally charged Chris Watts, 33, with their murders and also with allegedly terminating Shanann’s 15-weeks-old pregnancy.

The 30-minute video, filmed by Shanann on a Saturday morning at the couple’s Colorado home while Chris is seen playing with their daughters in the background, is an outreach to friends and clients of Shanann’s direct-marketing business as a seller of health supplements.

In it, she promotes her own growing confidence and independence while conceding she has battled through insecurities, including “health challenges” after she bought her first home at age 25.

“I met Chris because of those health challenges,” she says.

A mutual contact had sent her a Facebook prompt suggesting Chris as a possible friend. She deleted it. Two months later she received a diagnosis — her brother said she had lupus — “and I went through one of the, I would say, darkest times of my life, because things just got scarier.”

A North Carolina resident at the time, she quit her job of nine years, lost friends “because they didn’t understand that I looked perfectly fine, and I felt horribly inside,” and “was in a really, really, really bad place, and I got a friend request from Chris on Facebook,” she said.

“I was like, oh what the heck, I’m never going to meet him,” she said. “Accept.”

“Well, one thing led to another, and eight years later we have two kids, we live in Colorado, and he’s the best thing that has ever happened to me,” she said.
