When it comes to drama, Amber Portwood just can’t catch a break!

Throughout the entire season of Teen Mom OG, we’ve seen as the mother-of-one struggles with her relationship with Matt Baier, as their engagement has been plagued with nearly everything under the sun — from a drug relapse to cheating allegations.

On last night’s season finale, things finally came to blow when Amber got the results of a lie detector test. Things became particularly heated when it was revealed that he failed a question asking if he made any sexual advances to an unnamed woman; he said no, but the person conducting the polygraph revealed that he failed that question.

Check out the video to see how Amber reacted to the news.

Though they censored the name of the woman that Matt was accused of making sexual advances towards, a woman named Tiffany Bassett came forward saying that she had an affair with Matt after the two connected online.

She justified her experience as a means to expand her business as a tattoo artist, as she felt having a celebrity client, who was also allegedly willing to invest in her own studio, would be beneficial for her.

“Matt contacted me about investing in a new shop, and I was interested in telling my story in the process. I was excited to possible land a celebrity client, as well as a new business venture,” the mother-of-three and cancer survivor explained. “My motive was always business, and providing for my three children.”

Amber and Matt initially met online, and their relationship escalated quickly, with him moving in literally the first time they ever met. Just months later, he popped the question — though they made it clear they were in no rush to walk down the aisle and even called off their engagement on multiple occasions.

This time, it looks like Amber and Matt are done for good — and after all they’ve been through, we can’t help but think it’s for the best!
