Amber Portwood and Matt Baier were seen at odds during the premiere episode of Teen Mom OG season seven last night.

According to a new report, Portwood and Baier, who ultimately called it quits, were seen nearing the end of their romance as Baier shockingly admitted to suffering a drug relapse on the show — after he failed a lie detector test in regard to his alleged cheating months prior.

“Nothing’s changed at all so it’s hard,” she said. “I just feel like I’m trickling down a little with the relationship. I’m slowly going down as he keeps treating me like s**t. It’s nothing but stress.”

Portwood and Baier were involved in a strained relationship for the majority of season six and despite appearing to split at the end of the season, they seemingly picked back up where they left off during filming on season seven. However, while Portwood seemed hesitant to call it quits with Baier for good during season six, she appears to be ready to say, "Goodbye," during season seven.

Portwood's tense relationship with Baier began to affect her relationship with her daughter, 9-year-old Leah, who she shares with ex-boyfriend Gary Shirley. As fans of the show may recall, Shirley was seen discovering news of Baier's relapse and made it clear that he was unwilling to allow his child to be in a car with Baier.

Later on in the episode of Teen Mom 2, Portwood informed Baier that she no longer wanted to continue planning a future wedding and also said that she was considering calling off their engagement.

A short time later, Baier opened up about his drug relapse.

“Yeah I did drugs. I relapsed this year and I’m not ashamed of it. Why did I relapse? Because all of this bull s**t. You can only take so much of this s**t. I relapsed pretty f**king hard. I have no excuse for doing what I did… I was going through a bad time,” he said.

Following Portwood's split, she began dating Andrew Glennon, who she met while filming Marriage Boot Camp: Reality Stars, and is now expecting their first child. As the new episodes of Teen Mom OG continue to air, fans are expected to learn more about Portwood's new relationship and pregnancy.
