Amber Portwoodisn’t hiding her feelings.

TheTeen Mom OGstar posted a cryptic message about feeling heartbroken to her Instagram on Tuesday — nearly one month after she was arrested and charged with domestic battery.

“I am so heartbroken right now…omg?” she wrote alongside an image of a shattered heart.

“I love you so much,” Lowell wrote. “See [you] tomorrow.”

Portwood’s messages comes just one week after she hinted at the possibility of infidelity in her relationship with boyfriend Andrew Glennon. In a since-deleted post, she wrote, “Cheating is a choice not a mistake.”

Portwood, 29, was arrested and charged with domestic battery on July 5 after allegedly assaulting Glennon, 35, while he was holding their 1-year-old sonJamesin his arms.

On July 9, Glennon reportedly filed for sole custody of their son. And the following day, Portwood was further charged with domestic battery, criminal recklessness committed with a deadly weapon and domestic battery committed in the presence of a child less than 16 years old, according toPage Six.

Glennon alleged in the documents that Portwood “went to her drawer and took a handful of Klonopin and tossed it back like it was nothing,” during the dispute.

After he told her that he “was going to call for help,” Glennon said Portwood “regurgitated the pills.”

Then, Portwood “picked up a machete towards him and [James],” the documents read.

A source previously told PEOPLE thatdrugs were not a factorin thealleged violent dispute.

“The situation is a little more complicated than what’s been reported. There was an argument that escalated and now they aren’t allowed to communicate,” the source says. “There were no drugs involved.”

“This is a very challenging time for Amber, who loves her son more than anything,” the source added. “Now she will need to determine next steps following what just occurred, but she has a great lawyer.”
