Chris Watts' alleged gay ex-lover Trent Bolte plans to meet the Colorado killer in jail for one last time "for closure," the 29-year-old told Inside Edition in a recent interview. Watts killed his pregnant wife and his two daughters on Aug. 13, 2018.

Bolte told the Inside Edition that he met Watts on the dating app MeetMe in May 2017 before they became romantically involved. They were also planning on moving in together, during their 10-month relationship before Watts committed the crimes.

“We went and looked at houses together in Fort Collins,” Bolte said. “I was in the process of moving out of where I was staying. I was planning on getting a two-bedroom apartment, but Chris was like, ‘No, I’m going to be divorced. We need to look at three-bedroom houses and the girls can have a room.’”

Bolte, who initially presumed that Watts had separated, then later finding out about his marriage, said that he was sickened when his lover killed his pregnant wife Shan’ann and his two daughters, Bella and Celeste, whom he brutally strangled in their beds and dumped the children’s bodies in an oil tank.

“I think Chris is a monster, he definitely has the ability to be one,” he said. “Why didn’t he just divorce her? Why didn’t he listen to me? I mean, why [did he feel] like that was his only way out?”

Bolte said he plans to meet Watts in prison once his name is added to the visitation list, "just for closure for me."

"After that, I don’t want anything to do with him,” he said. “It’s not like I’m still in love with him, but I still view him as the Chris I knew.”

Watts pleaded guilty to murdering his 15 weeks pregnant wife and two daughters in order to avoid possibly getting the death penalty. He was sentenced to five life sentences in November 2018 and is not eligible for parole.

Earlier in December, Watts was transferred to Dodge Correctional Institution in Waupun — a facility known for notorious serial killers — following security concerns at his Colorado prison.

According to Candice DeLong, a former FBI criminal profiler and criminologist, Watts “is a malignant narcissist and psychopath.” In her opinion, “The hallmark is that they don’t feel remorse or empathy.” DeLong appeared on the “Dr. Phil” show last month where she spoke out about the killer.

Dr. Phil added to the conversation saying, “A narcissist actually thinks he can get away with it…And they get caught so easily because they don’t look at the other points of view.”
