AceShowbiz - Shortly after her separation from Jax Taylor in February, Brittany Cartwright, 35, secretly began a physical relationship with Julian Sensley, 42. Sensley, a former basketball player turned actor, was once rumored to be linked to "Vanderpump Rules" star Lala Kent.

An insider revealed that Cartwright and Sensley's romance was discreet and is now over. Sensley and his fiancee, who share a child, were reportedly experiencing difficulties during the time of his involvement with Cartwright.

When Jax Taylor, 45, discovered the affair, he reportedly became enraged, contributing to his decision to seek mental health treatment. Taylor spent August at an inpatient facility, where he was diagnosed with bipolar disorder, PTSD, and narcissism.

Upon his return, Taylor was served with divorce papers. Cartwright filed for divorce six months after the separation, citing a toxic relationship. Despite Taylor's previous infidelity and volatile behavior, a source close to the couple said he supported the decision.

Meanwhile, Taylor recently granted full legal and physical custody of their 3-year-old son, Cruz, to Cartwright. Taylor represented himself in court, listing their Los Angeles home as their only asset but requesting to divide it later. He also indicated that they were never legally married.

Despite their split, Cartwright and Taylor prioritize their son's well-being. Cartwright emphasized that Cruz's interests remain their main focus, even amidst any conflicts they may face.
