In the season finale of "Teen Mom OG," Farrah Abraham pressures her boyfriend Simon to propose to her, Simon deals with the bratty behavior of Farrah's daughter Sophia, and Maci Bookout fulfills her dream of buying her own house. 

In the episode, a very pregnant Maci wanted to make sure that she has a new house before giving birth to her second child. Along with her longtime live-in boyfriend Taylor McKinney, the two went on a house hunt, and eventually, they found their dream house. The house, which cost them $155,000, has everything she ever wanted: three bedrooms, a yard where her son Bentley can play ball, and even some space for Taylor where he can have his man cave. 

The couple knows that they made a big step in purchasing their home, as Maci said after putting in an offer for the house, "We're like for real adults." 

Indeed, Maci has come a long way since her first season on "Teen Mom." She was able to go back to college and is now months away from becoming a college graduate, with not just one, but two degrees. She is currently enrolled at Chattanooga State Community College and is getting a major in Media Technology and a minor in Creative Writing, all while raising her son. She is also currently expecting her daughter Jayde Carter in June. 

Maci talked about the house in the "Teen Mom OG: Featured Moment" clip on MTV, wherein she said that the house is "everything that we were looking for, luckily." 

"My hopes for our future in our house is that we continue to like it or love it as much as we do right now," she said. 

Meanwhile, things did not look so well for Farrah during the show's finale. She told Simon that she doesn't want to live with him until they get married, but Simon told her that he needs about two years more before he starts thinking about engagement. 

In an attempt to speed up the process, Farrah decided to introduce Simon to her daughter Sophia, in hopes that they might bond. However, as soon as Simon got into the car with them, Sophia immediately started acting up, choking Simon with his seatbelt, slapping him, and, at one point in the episode, she even waved a butter knife at him. Later, Farrah noted that Simon doesn't seem too happy to be with them. 

To explain his behavior, Simon took to Twitter on Tuesday, May 26, to apologize to Farrah and to Sophia.

He wrote, "Due to the bad mood @MTV had put me in during filming, I want to apologize to @F1abraham and Sophia as I love and care for the both of them."

Farrah retweeted his message, and it appears as though things are still going strong between the two of them.
