In a sneak peek of the Feb. 11 episode of ‘Teen Mom 2,’ we see Leah Messer dealing with ex Corey Simms’ denial over their daughter Aliannah’s congenital muscular dystrophy diagnosis. It’s a powerful, emotional scene that leaves Leah fighting back tears as Corey refuses to accept how difficult Ali’s future will be.

On the Feb. 6 episode of Teen Mom 2 we witnessed Leah Messer, 21, and her ex Corey Simms, 24, receive their three-year-old daughter Aliannah‘s congenital muscular dystrophy diagnosis. The doctor also informed the family that it was likely that Ali would need to use a motorized scooter in the near future, especially if she planned on attending school. During the follow-up Feb. 11 episode, Leah is faced with yet another difficult task — breaking Corey out of his denial of the situation.

‘Teen Mom 2′ Preview — Leah & Corey Disagree Over Ali’s Diagnosis

In a clip provided by MTV, Leah tries explaining to Corey why Ali needs to be evaluated and enrolled in school as soon as possible so that she can begin her education in the fall. Corey seems confused as to why Ali would go to school alone and not with her twin sister, Aleeah. Once Leah realizes that Corey isn’t just confused, he’s also in denial about Ali’s condition, she tries to explain that it’s not going to get any better and they have to accept that now. It’s a sad clip that gets emotional very quickly, especially when Leah goes silent while holding back tears as Corey tries to justify his denial.

Chelsea & Adam Pick Up Aubree From School

In another clip from the Feb. 11 episode of Teen Mom 2, Chelsea Houska continues to work on involving her ex Adam Lind in their 4-year-old daughter Aubree’s life by inviting him to pick her up from her first day of school. The special day just so happens to coincide with Chelsea’s 22nd birthday, which Adam has of course forgotten.

Even after he is reminded that it’s Chelsea’s birthday, Adam selfishly invites Aubree to spend the rest of the afternoon with him without checking to make sure Chelsea doesn’t have any special plans first.. Chelsea is quick to intervene before Aubree gets her hopes up, but Adam is confused as to why he can’t take his daughter home with him.
