Amber Portwood says she's "working things out" with her fiance Matt Baier. The 27-year-old "Teen Mom OG" star confirmed she's still living with Baier in an interview published Monday with E! News after appearing to announce their split this week. "We're working things out. We're working on our issues," she said. "That's all that needs to be said." Portwood had told fans in an Instagram Live video Sunday that she and Baier were longer together. "We are not together. Matt has some issues he needs to work on and then we can see what happens," she said, according to The Ashley's Reality Roundup. Portwood and Baier became engaged in March 2015 after dating for less than a year. E! News reported in May that the reality star postponed her fall wedding to Baier in order to work on their relationship. "For the time being, Matt and Amber's engagement is on hold," a source said at the time. "They are working on their relationship. "A lot has come out through the course of filming and from various online stories. That has added extra pressure and made things difficult," the insider explained. "Despite their issues, they are still living together and are hopeful things can be fixed." Portwood called off her nuptials to Baier on Monday's episode of "Teen Mom OG" after Baier gave her co-star Catelynn Baltierra a Xanax while the cast was in New York. She dismissed Baier's apology on the show, saying she was fed up with his mistakes.
