"I'm not willing to live like I've been living," says Tamar in the sneak peek.
The "Tamar & Vince" sneak peek highlights some of the struggles between the singer and her manager/husband, shedding light the issues going on with the duo behind the scenes.
"With everything that I've been through this past year, I have chosen to overcome," Braxton says in the video. "Gotta cut out the noice, the negativity, the naysayers. I need everybody to put their pride aside and just reunite."
Braxton is then seen putting her words into actions by first telling her friend Tiny Harris that she wants to be her "own CEO of [her] life." Shortly after, the reality star is seen yelling that she wants to manage herself.
"I think Tamar's going through a midlife crisis," Herbert says in the clip. "I think you should get another manager before you want to get another husband," Harris adds.
The trailer ends with Tamar taking off her wedding ring as she says, "I'm not willing to live like I've been living."
Tamar filed for a divorce after nine years of marriage on Tuesday. A rep told TMZ: "At this time we can confirm Ms. Braxton has made an extremely difficult decision and has filed for divorce from Vincent Herbert. Collectively, their son Logan and his well being during this very unfortunate process is most important. We ask that everyone respects her privacy during this very difficult time. She appreciates everyone's love and prayers."
The two have been married for nearly 9 years.
