Amber Portwood and her boyfriend, Andrew Glennon, are keeping their finances "completely separate" from one another -- and for good reason.

After Portwood was seen slamming her former fiancé, Matt Baier, on Teen Mom OG for allegedly stealing thousands from her during their years-long relationship, the pregnant reality star is speaking out about the dynamic between herself and Glennon.

“With Matt, we had joint accounts, businesses together, things like that, and I’ve learned my lesson," she explained to Us Weekly magazine on March 15. "My money is my money, and when we’re together, we can help each other and be there for each other and take care of this child."

How Did They Meet?

Portwood and Glennon began dating after meeting each other last summer as she and Baier filmed the currently airing season of Marriage Boot Camp: Reality Stars Family Edition. As fans may have heard, Glennon was working on the show as a lighting techinician and quickly fell in love with the Teen Mom OG star.

In August of last year, just after wrapping production, Portwood showcased her romance for the first time on Instagram and days after that, she and Glennon debuted their romance on the MTV Video Music Awards' red carpet. The following month, during a visit to Hawaii, Portwood learned she was expecting.

While Glennon is certainly capable of caring for Portwood and their baby boy, who is due in just a couple of months, he appreciates that Portwood is financially stable in her own right.

Amber Portwood Is Genuinely Hhappy

Continuing on to Us Weekly magazine, Portwood said she was quite happy that after years of back and forth with Baier, she finally has a "calm" and "chill life." She also noted that she's genuinely happy for the very first time. 

What Does The Future Hold for 'Teen Mom OG'?

As Portwood and Glennon prepare to welcome their first child together, the second for the reality star who also shares 9-year-old Leah with Gary Shirley, the future of Teen Mom OG appears to be up in the air. As fans likely saw, Farrah Abraham was released from her contract with the network on Monday's new episode and now, rumors are swirling the web suggesting that Teen Mom 3 star Mackenzie Standifer may be preparing to replace her.
