Flip or Flop star Tarek El Moussa admits there was one aspect of his relationship with Christina El Moussa they could've worked on to possibly save their marriage.

"I feel like if we had better communication, we would have had a better relationship," Tarek, 35, said in a clip released by The Doctors of Monday's episode.

Tarek, 35, and Christina, 33, publicly announced their split after seven years of marriage in December, and then he filed for divorce on January 9.

"I think as time went on, as you get busier and busier -- and, you know, it was like overnight. Businesses, TV, all these things happened overnight, and then the cancer, then the cancer, then the back surgery. It just kind of started pushing us apart from each other," Tarek explained, revealing that several years of issues led to the demise of their marriage.

"I had thyroid cancer in 2013. One month later they found out I had testicular cancer. It was very difficult on me. My hormones were way off. It affected me. It's been three years of hell. I was devastated when I found out. So was Christina."

Shortly after Tarek's battle with cancer, Christina went through an infertility struggle in which she underwent rounds of in vitro fertilization.

The parents of Taylor, 6, and Brayden, 18 months, initially separated in May 2016 as a result of an incident in which authorities were called to the couple's home to check on a "possibly suicidal male with a gun."

Christina was bawling her eyes out after Tarek allegedly fled the house in a fit of rage. The pair, however, eventually called the event that prompted their split an "unfortunate misunderstanding."

Tarek repeated during his interview on The Doctors that there was simply a "misunderstanding" that day, explaining, "I have a CCW [carrying a concealed weapon] permit in California. I've gone through the training, the schooling and everything."

Tarek has told multiple media outlets that he went for a walk to blow off some steam and brought a gun with him only for protection against wild animals and such. After the May events, Tarek and Christina began dating other people.

Despite all the hype surrounding their divorce and reports of drama on the set of their HGTV reality show, Tarek and Christina continue to film Season 7 of Flip or Flop and attempt to amicably co-parent their children, who remain the pair's main priority.

Several days ago, Tarek posted a photo of the estranged spouses smiling for the camera with the following caption and laughing emoticons: One #lucky lady!!!!! Another #FliporFlop house down!! Time to....... find another house to flip." Tarek added a winking emoticon at the conclusion of his post.
