'We Just Need To Separate!' Ryan Edwards Admits Wanting To Leave His Pregnant Wife Mackenzie

The season finale of Teen Mom OG brought a lot of tears! From a new baby to the same baby daddy drama...click through for the biggest O-M-G moments from tonight's episode.

Watch the highlights here!

Ryan Edwards and his wife, Mackenzie, are expecting their first child together and the drama is only getting started! Mackenzie revealed how she told Ryan about the exciting news when the two ordered McDonalds. She put her positive pregnancy test inside his bag and was shocked when he found it.

The two headed to a doctor's appointment to check on their little bundle of joy, which is due October 15th! Following the check-up, things quickly went south for the couple. The couple didn't leave with the best attitudes, and it exploded inside their home.

After returning home, Ryan questioned if it was cold inside their house and Mackenzie fired back, "NO!" Ryan told her that she had an "attitude" and she replied, "Because you're a d**k!" "I just don't know if I can do this for 9 months with you," he said. "I think we just need to separate for 9 months."

Despite their baby news, Ryan's first baby mama, Maci Bookout, still isn't sure that he is "clean" following his stint in rehab for heroin addiction.

The mother-of-three told her mother, Sharon, that Ryan has yet to pass a drug test to spend more time with their son, Bentley. "He still hasn't a passed a drug test right?" Sharon asked, which Maci nodded her head no to. "Well that's not a good sign. Let's face it, if he was clean, he would take the drug test." Maci added, "My people know people...he's not clean. He's not. That's just it. He's not."

Catelynn Lowell is back home...but not feeling her best! Back in November 2017, Cate checked into treatment after having suicidal thoughts following her tragic miscarriage with her husband, Tyler Baltierra. After returning home, Cate planned out her outpatient treatment to further help her recovery. She explained to Tyler that she will go back to seeing her therapist, their psychiatrist, getting a new phone with no social media, riding her horse, and spending more time with their daughter, Nova.

However later on, she opted to return to treatment after realizing her medication wasn't working. Tyler was left in shock with his wife's news, but assured her he wasn't going anywhere when she mentioned the word divorce. Tyler was supportive with her decision, but wasn't sure if it was the best option because of their daughter.

Tyler went to dinner with his sister, Amber, and expressed his shocking thoughts about Cate returning to treatment in Arizona and leaving their daughter, Nova, for weeks again. "I feel like she did not weigh any options, it was just..boom, leaving, going, bam...that was it," he explained. "In my opinion as Nova's father, I think outpatient is what's best for Nova, and I think inpatient is what's best for Cate, and she looked at me and she was like, 'she'll manage.'" Tyler admitted to Amber that he was so taken back by the comment especially since their daughter is 3-years-old. He even compared it to his situation with his dad, Butch, who was in and out of his life growing up to his battle with drug addiction. Amber questioned that maybe Cate is "scared" to talk to Tyler about the issue more in-dept, and he didn't take it well, suggesting that maybe he "isn't good enough" for Cate.

In the end, Cate leaves for her third rehab stint.

Amber Portwood's due date is approaching so she is trying to spend quality time with her daughter, Leah. Unfortunately, the pregnant reality star was facing problems when her 8-year-old was wanting to spend more time with her friends over her mother.

Amber was angry since her first baby daddy and ex-fiance, Gary Shirley, refused to switch weekends with her. She and Andrew Glennon discussed with their producer their frustration when it comes to co-parenting with Gary since he isn't as flexible with Leah's schedule as they would like to be.

While talking to her producer and second baby daddy, Andrew Glennon, she explained that people have suggested that she takes Gary back to court, however, she didn't look at that as the best option. "My kid is 9-years-old, I'm taking taking her away from where's she been for years, where she has her stepsister, and her other baby sister. You don't just take the kid away from something like that...that's like trauma. So if he doesn't cooperate with giving me extra time, that is something I am going to have to modify."

Despite having issues now, Amber is looking forward to the future! While talking with her cousin, Krystal, she revealed that she would love to hop on a plane and move to California...but her daughter is of course the reason why she is staying in Indiana. She explained that in the future after Leah graduates high school, she plans to get up and move!
