Tensions are going to rise in the upcoming episode of Teen Mom OG. In season 6 episode 9 titled The Tipping Point, Tyler Baltierra and wife Catelynn Lowell have a showdown after her return from the rehab.

Tyler, scared and anxious about his wife's mental health, becomes tough on her. The 24-year-old tells his wife that she needs to get her life back together and engage herself in activities that are constructive. 

This tough talk is really a result of Catelynn's incessant complaints about being bored at home. Novalee's mother says that Tyler's talk is going to give her a panic attack but Tyler doesn't back off. 

"You know what? I am sick of hearing that," Tyler says in the promo for season 6 episode 9.

He also states that her behaviour could destroy their marriage. He threatens to "check out" of their relationship. 

"I'll get hardened. I'll close everyone off. It's safe that way," Tyler adds. 

It was only a while ago that Catelynn returned from rehab. The reality star, who admitted herself to treat her anxiety, was given a warm welcome by her husband. In an earlier episode, Tyler said he was proud of her being courageous and strong.

However, Catelynn has been struggling with marijuana addiction since her return from the rehabilitation centre.

Season 6 episode 9's synopsis (via TV Guide) reads:

Amber, who fears that she's developed a new addiction to food, consults a doctor about her weight; Farrah wants to open a frozen yogurt shop; Tyler worries that Catelynn has fallen back into bad habits; and Ryan leaves home after a fight with his dad.

Teen Mom OG season 6 episode 9 airs at 9 pm EST on Monday, October 11, on MTV.
