Her ex recently opened up about his decades-long struggle with substance abuse, revealing that he's over 83 days sober from cocaine and alcohol.

"I'm glad that he finally admitted to what was really going on," Brittany told People in a March 4 statement following Jax's bombshell confession. "For the first time, I can speak openly about the extent of trauma he's instilled on our family over the years."

The Vanderpump Rules alum, who shares 3-year-old son Cruz with Jax, went on to share that she had tried to help her costar with his addiction issues for years, but it had always been "without success."

"I pray that one day he completely knocks this addiction, but I'm skeptical," Brittany, 36, continued. "His behaviors are still alarming and his treatment plan seems to be the bare minimum."

She added, "I'm trying to navigate this as best as I can for my son and I, but every day is still a challenge and very difficult. Jax has caused an enormous amount of damage and I have very little trust in him at this point. My only hope is that one day, he will be a better person for his son."
