AceShowbiz - The much-anticipated second season of "The Valley" has returned, diving deep into the tumultuous separation of reality stars Brittany Cartwright and Jax Taylor. Picking up nearly nine months after their initial split, the series reveals the couple's unresolved tensions and explosive altercations.

In a shocking premiere on April 15, viewers are immediately thrust into the chaos that defines Brittany and Jax's current relationship. As Jax, 45, recounts in a confessional, "It's not going well. She's in a rental and we're allowed to date other people. I mean, it's so toxic. It's so broken."

The source of their tension is clear: trust issues and misjudged boundaries, especially regarding Brittany's communication with Jax's former friend, Julian.

The discovery of text messages between Brittany and Julian, along with a provocative video, set off a series of violent outbursts from Jax. Brittany, 36, shares her harrowing experience with co-star Michelle Saniei.

She described Jax's reaction, "He flipped the coffee table and it hit my knee. It turned black immediately. I'm like, 'Oh my God, oh my God.' Screaming, crying. It was terrifying."

This violent response was exacerbated by Jax's perception of betrayal, despite their agreement to see other people during their separation.

Jax admits to his violent outburst, describing it as an "unhinged" moment of rage. He reflects on the incident with Jesse Lally, revealing, "I went full f****** unhinged rage on Brittany. That's the worst it's ever gotten."

His behavior has even left him doubting his capabilities as a father, acknowledging the profound impact his actions could have on their 4-year-old son, Cruz.

Echoing Jax's concerns, Brittany asserts that she cannot allow Cruz to be around his father unsupervised due to Jax's escalating rage. Despite these challenges, both Jax and Brittany agree that reconnecting with friends was never a part of their separation arrangement - a point of intense contention between them.

Amidst the chaos, Jax has sought professional help to manage his anger and mental health. He completed a 30-day in-patient treatment program and revealed that he has been diagnosed with bipolar disorder and post-traumatic stress disorder.

As he marks 83 days of sobriety from cocaine and alcohol, Jax's journey highlights the importance of seeking help and making necessary changes for oneself and one's family.

Get update on Brittany and Jax's unraveling relationship as "The Valley" is airing Tuesdays at 9 p.m. ET on Bravo.
