A close friend of Shanann Watts said the pregnant murder victim struggled with her suspicion that her husband — now accused of killing her and their two young daughters — had been cheating on her.

As CrimeOnline previously reported, some sources indicate Chris Watts had been carrying on an affair with a colleague prior to the triple homicide earlier this month.

According to People magazine, Nicole Atkinson said her friend “didn’t want to believe that” her husband was unfaithful.

The woman, who was among the last to see Shanann Watts alive, said the victim told her that her husband “wasn’t being the loving Chris that he normally was.”

Atkinson went on to describe the type of unusual behavior she said her friend told her about.

“He wasn’t touching or hugging or doing stuff like that,” she said. “And he wasn’t being as attentive to the girls as he normally is.”

An affidavit released in the case, indicated that the suspect informed the victim that he wanted to end their marriage shortly before she disappeared with the couple’s 3- and 4-year-old daughters.

CrimeOnline previously reported that Shanann Watts shared a video on social media in which she fondly recalled how she met her husband.

“I got a friend request from Chris on Facebook and I was like, ‘Oh, what the heck, I’m never going to meet him,’” she said. “Except, 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.”
