Since 'The Real Housewives of Atlanta' star's estranged husband Kroy Biermann filed for divorce on May 5, things have gotten increasingly complicated between the exes

Kim Zolciak-Biermann appears to be reflecting on her increasingly complicated divorce from husband Kroy Biermann.

The Real Housewives of Atlanta star shared a cryptic quote on her Instagram Story Thursday that could easily be read as a comment on the current state of her personal life.

"Manipulation is when they blame you for your reaction to their toxic behavior," the quote read, "but never discussed their disrespect that trigged you."

And while the quote wasn’t something she wrote herself, Zolciak-Biermann, 45, added the comment: "READ THAT AGAIN…"

The former NFL player, 37, filed for divorce from Zolciak-Biermann on May 5. In his court filing, Biermann requested sole legal and physical custody of the pair's four minor children: 9-year-old twins Kaia Rose and Kane Ren, plus sons Kash Kade, 10, and Kroy Jagger, 11. (He previously legally adopted Zolciak-Biermann’s eldest daughters, Ariana Biermann and Brielle Biermann, in 2013.)

Zolciak-Biermann submitted a separate filing to the court on May 8. She requested primary physical custody of their children with joint legal custody. She is also seeking spousal support and the restoration of her maiden name.

Recently, a source told PEOPLE that "everyone expects this divorce is going to get really bad because neither of them will give in." And ever since submitting their respective filings, that has been the case.

PEOPLE obtained court documents of Zolciak-Biermann’s request for Biermann to "submit to a five-panel hair follicle drug screen." Per the documents, Zolciak-Biermann claiimed to have witnessed Biermann smoking marijuana and because of that, she is "fearful" and "has serious concerns for the safety and well being of the minor children" under his care.

But Biermann countered her filing with his own request to the court for a Motion for Psychological Evaluation.

The document alleged that Zolciak-Biermann "presented very troubling behavior which has accelerated in the months leading up to Petitioner's filing for divorce." He also claimed that his estranged wife "acknowledged spending substantial time and marital funds on gambling and other games of chance," and that her alleged gambling issue has supposedly "financially devastated the parties."

A source close to Zolciak-Biermann told PEOPLE at the time: "She's been gambling, that's true, but she has been winning. He is just trying to make it look like she has been losing money."
