'This decision wasn't made lightly but she feels adamant that it was the right one,' the insider added. 

The source noted that Jax has 'mixed emotions' about the filing, but knows it's 'ultimately the right decision.' 

 The Vanderpump Rules star filed the divorce documents Tuesday after five years of marriage, as per legal documents seen by DailyMail.com. 

She cited irreconcilable differences as her reason for ending the marriage. 

DailyMail.com has contacted a representative for Cartwright and NBCUniversal, Bravo's parent company, for comment. 

Cartwright and Taylor, 45, who wed in a lavish wedding that aired on Vanderpump Rules, have a three-year-old son Cruz together. 

Brittany has requested primary legal and physical custody over the child however is open to visitation for her ex. 

Additionally, Cartwright is seeking to block the ability of the court to award either one of them with spousal support. 

Cartwright cited their date of separation as January 24. 

The couple's early romance was chronicled on the Bravo series Vanderpump Rules and the breakdown of their marriage was captured on the spin-off, The Valley, with Cartwright revealing she had moved out their marital residence with son Cruz.

'A lot has happened with me and Jax,' Brittany said in a confessional. 'We were already having issues all summer long, but once the cameras stopped rolling, things just seemed like they were getting worse and worse and worse.

'So about six weeks ago, I separated from Jax. I moved into an AirBnb with Cruz because Jax would not leave the house,' she said on the finale.

Brittany said that Jax not moving out showed his selfishness. Brittany said she left with their three-year-old son Cruz because the situation at home was toxic. Brittany said Jax would come with a hangover and in the morning would be 'mean as a snake.'

'I just hit this point where I just started noticing everything that he did to me,' Brittany said. 'It just hit me like a ton of bricks.'

Brittany said during their relationship that Jax cheated on her, disrespected her and humiliated her.

'I have been through a lot of pain in this relationship,' Brittany said. 'I just can't deal with it anymore.'
