But when asked whether their relationship is stronger than ever, Pedro replied, "We are working through things at this point, working through things."
"We still have things that we don't agree on yet that are still there," he added.
"I agree. I feel like we still have a long way to go," Chantel told ET. "Well, not a long way to go because we've been married for a few years, but it's always a work in progress. We can't stop trying and getting better."
Of the couple's lingering issues, their sparring families is unsurprisingly one of them.
"Family issues, are they ever ending? Like, they're never ending and I feel like that's an ongoing thing that you have to continuously work at," Chantel shared.
"And I mean, hopefully certain things will all just come out in the wash because you have to get over certain things and let them go, so, family is definitely still an issue with us."
Chantel continued, "But as far as him and I personally, I feel like we're getting in a better place with our trust right now. I feel like we've made a lot of progress."
The pair, for instance, said they've made amends for some of their mistakes. Chantel revealed she had apologized to Pedro for yelling at him after watching unflattering footage of herself back on The Family Chantel.
At the end of the day, Chantel said spending quality time with Pedro has been "great" for them.
"It's done a lot for our relationship," Chantel noted. "We have deeper conversations with one another now."
"You can't go anywhere," Pedro added with a laugh. "You can't escape."
As much as Pedro tried to improve his relationship with Chantel's parents on The Family Chantel and Karen Everett and Thomas Everett worked to make Pedro feel accepted and welcome, an insider told In Touch Weekly in December 2019, "Pedro still can't stand Chantel's family and vice-versa."
"They don't talk often and it doesn't seem like they will make amends any time soon. Pedro is focused on bringing his mom and sister to the United States," the insider added.
Pedro's mother Lidia and sister Nicole both currently live in the Dominican Republic but have been hoping to move to the U.S. so they can be with Pedro -- who lives with Chantel, 29, in Atlanta, GA -- and purse the American dream.
Chantel and Pedro told E! News in July 2019 their relationship was still going strong.
"We have our differences that we're still working on. We have our challenges, but that's something that will play out on the show," Chantel said at the time.
"There is no such thing as a perfect relationship, and we have our flaws."
Despite their flaws, Chantel also told People in late July if she could go back and do it all over again, she'd still choose to be with Pedro and endure the struggles they've had.
"I would still choose to marry him, but I would definitely have more realistic expectations," Chantel admitted.
In addition, Chantel and Pedro were also spotted attending the corporate holiday party of TLC's Discovery Inc. parent company in New York City in December 2019.
Chantel and Pedro, who met online over four years ago and got engaged after Chantel visited Pedro several times in the Dominican Republic, originally appeared on Season 4 of90 Day Fiance on TLC.
Once Chantel's family learned Chantel would be getting married after a whirlwind romance overseas, they were suspicious Pedro was after Chantel's money and/or a Green Card.
Chantel's family also thought it was strange Pedro was frequently sending money home to Lidia and Nicole in the Dominican Republic.
To ensure Pedro wasn't keeping any secrets or living a double life, Chantel's family hired a private investigator to research his background and also demanded the couple sign a prenuptial agreement in order to protect Chantel's financial interests before their wedding.
Pedro hated that Chantel's family didn't trust him, but Pedro's mother and sister weren't fond of Chantel either and disapproved of their relationship.
Pedro and Chantel later appeared on Seasons 2, 3 and 4 of 90 Day Fiance: Happily Ever After?.
Tension between the two families exploded during the third season of 90 Day Fiance: Happily Ever After?, when Pedro got into a blowout fight with Chantel's brother River at the dinner table and then Nicole accused Chantel's family of attacking her in their home.
Neither side ever budged on offering an apology, so there was a standstill between families that resulted in more confrontations and disagreements down the road, as no one agreed upon who was to blame.
Problems between Chantel and Pedro also came to a head when Pedro visited his family in his native country, only to get caught dirty dancing with Coraima. Pedro's mother and sister also blamed Chantel for taking Pedro away from them and being a selfish wife.
But Chantel's family accused Lidia and Nicole of setting up Pedro's relationship with an American, who turned out to be Chantel, so Pedro would have more opportunities to make money and they could eventually move to the United States as a family.
Chantel's parents viewed Lidia and Nicole as being manipulative and dishonest about their intentions.
On The Family Chantel spinoff, which wrapped in September 2019 on TLC, Pedro felt alone in the United States, and even family counseling didn't seem to help the dynamic between Pedro and Chantel's family.
The Family Chantel featured both families gathering together twice in the Dominican Republic in order to hopefully talk out their issues and find peace, but mean words were thrown around and screaming erupted.
Chantel vented in one episode, "They're not receptive to any kindness. I hope all dogs go to heaven because Pedro's mom and sister are complete b-tches. There's no way [they're] going to be living with me under the same roof -- ever."
Having a language translator helped during the second meeting, but it appeared enough damage had been done to prevent truly amicable relations in the future -- until both families came together and had a friendly visit with Pedro's sick grandmother.
However, the finale of The Family Chantel showed Chantel throwing a drink at Coraima following a heated discussion about Pedro's wild night out in the Dominican Republic.
Nicole naturally took Coraima's side, and so Chantel realized any improvement in her relationship with Pedro's sister had just been destroyed. However, Pedro had Chantel's back.
