Amber Portwood DUMPS Matt Baier In Explosive Fight: 'You're Sorry Every Other Week!'

Amber Portwood is finally taking a stand against her controversial fiancé. In a Teen Mom OG sneak peek, Portwood called off her wedding to Matt Baier after a season of doubts.

Earlier in the season, Portwood had cold feet about marrying Baier because of trust issues after he was busted lying about having at least nine children with seven different women. But the mother of Leah, 8, finally had enough.

"I'm really sorry about last night. Do you forgive me?" Baier asked, as Portwood responded, "You're sorry every other f*****g week!"

When he asked if she would still marry him, she responded, "no."

"Do you mean that? You're not going to marry me?" he asked. "Baby come on I'm sorry. I made one mistake."

She then fired back, "You've made more than one f*****g mistake. I'm not doing it."

When he said that he wouldn't do it again, she informed him that her microphone has been on.

"You should've f*****g known that," she told him of the recorded conversation. "Your ignorance."

As RadarOnline.com reported, Portwood broke off their engagement in May after sources revealed that he failed a lie detector test about cheating on Portwood.

Although an insider told RadarOnline.com that the reality stars are "still living together" and that Portwood has "not made any final decisions just yet," she revealed over Instagram live that they are not together.
