Darcey and Stacey Silva are thankful for the therapy they received on 90 Day: The Last Resort.

Stacey and her husband Florian Sukaj attended the couple’s retreat in Arizona in hopes of working on their relationship. Eventually, Darcey joined her twin sister at the retreat for some “deep” therapy, as well.

Speaking exclusively with PEOPLE, Stacey admits she and her sister were “in dire need” of some joint therapy.

“It was a blessing to have her at the retreat and get some counseling,” Stacey explains. “And I really feel like it’s helped us since then, since coming back from the resort.”

Adds Darcey, “We’re very resilient and we’re family, so we have to have each other’s back at the end of the day.”

Tensions rose between the twins shortly after Darcey arrived at the resort. Stacey felt Darcey had overstepped the boundaries of her marriage to Florian, pointing to the multiple late-night meetings and conversations her sister had with her husband.

At one point, Stacey angrily asked her twin “Do you want to f— my husband?” But Darcey later insisted she would “never” have imagined doing such a thing “in a million years.”

Darcey later expressed concern about the future of her relationship with Stacey. “If we don’t fix this s— now, we’re gone. We’re done,” she said at the time.

Stacey admits their fight was one of the most emotionally impactful moments of the retreat. “That was really bad,” she says.

Darcey tells PEOPLE she wanted Stacey to succeed, but also wanted to feel heard.

“I think we get triggered and play the blame game a little bit,” Darcey confesses. “But at the end of the day, we shouldn’t be doing that. We should just be rising above and being a dynamic duo and a force to be reckoned with.”

Stacey tells PEOPLE she “learned a lot about myself” on Last Resort, and Darcey says she “was glad to be a part” of her sister’s journey.

“At the end of the day, we only really have each other besides the relationships we have with husbands,” she says. “So I think staying strong and kind of going through some of the moments that trigger us at times and working on that is a blessing too.”

Both twins are grateful for their time at the retreat. “For us, being vulnerable is healing, and this journey was very healing,” Stacey says.

“At the end of the day, we love each other and we want to work out our issues for the better,” she adds.

When asked to describe their current relationship in one word, the twins agreed on “fun-loving.”

“I feel like after the resort, we’re in a different era in our life and we are embracing our 50s,” Stacey says. “We are having fun with it and just enjoying every single moment of our life.”

Adds Darcey, “We elevated for sure. We’re raising the bar. And hopefully it’s an inspiration to others as well.”
