Teen Mom OG: The Moment Amber Portwood Was Forced to Pause Her Wedding Plans with 'Junkie' Fiancé Matt Baier

Was this the moment that almost broke Amber Portwood‘s wedding plans with Matt Baier?

On Monday’s episode of the MTV hit series Teen Mom OG, Portwood, 27, was forced to make a difficult decision when she became aware of Baier giving Catelynn Baltierra a Xanax when her costar began to experience a panic attack while they were in New York City.

Portwood, who in her own words began to “freak out,” halted their wedding, stating that Baier was supposed to be sober and not in possession of any drugs.

When Baier approached Portwood to pull her aside (from what looked to be a hotel lobby), he asked if she’d forgiven him, to which she responded, “No.”

“You’re sorry every other f—— week,” she told him.

“Will you still marry me?” he asked Portwood. When she shook her head no, he expressed his shock, and asked, “Do you really mean that?”

“What about all these questions you’re going to get today?” he inquired, referring to the press day the Teen Mom OG stars were in New York City for.

“I’ll lie right now if they ask,” she said. “You made more than one f—— mistake, I’m not doing it.”

Later, Baier approached Catelynn with an apology for causing a mess, and explained that a friend of his had given him the Xanax in case Portwood needed it on the plane. Baltierra tweeted after the episode aired, and clarified that she did not take the Xanax Baier had offered her.

Baier also spoke to an MTV producer, when he recalled how Portwood had called off their wedding that morning: “She wakes me up this morning, [saying], ‘We’re not getting married. You’re a f—— junkie.’ I go, ‘What the f— is going on? I didn’t do a f—— thing wrong.'”

“I’m done with this,” Baier added. “I did not deserve what happened to me yesterday. God knows what she is saying in these interviews right now. Give me five minutes with the press — I’ll tell them what she’s really like.”

Speaking to her fellow costars, Portwood admitted she and Baier had never been to therapy together, despite her expressing a desire to go before they tied the knot.

Meanwhile, the other moms dealt with their own life changes.

Tyler and Catelynn adjusted to their daughter, Nova, attending pre-school for the first time. Farrah Abraham invited her ex, Simon, to attend a hypnotherapy session with her, intent on helping him get over her. Maci Bookout and her husband, Taylor McKinney, went golfing for his birthday, following their therapist’s orders to take some time for themselves. Later, Bookout surprised him with a party at their home.

Teen Mom OG airs Mondays (9 p.m. ET) on MTV.
