Khloé Kardashian and Tristan Thompson's relationship never fully recovered from his first cheating scandal, a source tells PEOPLE

Khloé Kardashian and Tristan Thompson‘s relationship was hanging on by a thread before the latest round of cheating allegations.

The couple endured their first public scandal last April, when videos surfaced of Thompson, 27, getting close to other women just days before Kardashian, 34, gave birth to their daughter True. Though the new mom initially forgave the basketball player, a source tells PEOPLE their relationship never fully recovered.

“Since True was born, things never really went back to normal with Tristan and Khloé,” the source says. “She was deeply hurt by him and basically kept him at arm’s length. One of the only reasons she was still seeing him was because of True.”

The couple officially called it quits after Kardashian heard Thompson was allegedly once again unfaithful, this time with her sister Kylie Jenner‘s best friend, Jordyn Woods.

“The fact that her family is breaking apart is a nightmare for her, but it’s been a long time coming,” the source says. “They’ve been living separate lives. She can’t trust Tristan, and she’s known that for a long time. She’s been focused on her daughter and creating a loving healthy home for her. She doesn’t deserve this and she knows it.”

When the news broke, the reality star deleted any trace of Thompson from her Instagram since True’s birth in April 2018, including a family photo of the trio taken on Thanksgiving.

While she still follows him on Instagram, the most recent picture of him on her feed is from April 9, 2018 — just before the first round of cheating allegations. She did unfollow Woods, however.

After doing the social media sweep, Kardashian shared a series of emotional quotes to her Instagram Story.

“The worst pain is getting hurt by a person you explained your pain to,” the first quote read.

Another slide read, “Somebody needs to hear this…That betrayal was your blessing.”

Within an hour of the cheating reports, the NBA star issued an apparent denial, writing “FAKE NEWS” in all caps before deleting the tweet.

A source told PEOPLE that the Kardashians found out about the scandal Monday.

“The whole family is furious,” the source said. “They were blindsided.”

Reps for Kardashian and Thompson have not returned PEOPLE’s requests for comment. Woods’ rep had no comment.

And while the alleged affair feels like a deep betrayal for Kardashian, the rest of the family is hurting as well.

“It’s all a mess now. Everyone considered Jordyn family. She was like a family member and always invited everywhere,” a source told PEOPLE. “The family helped her and wanted her to be able to have a business venture too.”
