We can not believe how quickly the co-parenting situation is disintegrating between Leah Calvert and her ex, Corey Simms - and it sounds like they're pretty shocked, too.
In this sneak peek from this week's Teen Mom 2, Leah and Corey are arguing about their daughter Ali's wheelchair because Corey's insurance has been very slow in responding to their requests.
Corey argues that he thinks therapy is just as important and blames Leah for the fact that her therapy got cut off after she missed two sessions.
A stunned Jeremy (Leah's husband) says he doesn't understand how their co-parenting suddenly "went to s**t," and that just seems to make everyone more mad.
Corey blames Leah, Leah blames Corey and when Corey says they should all talk more, Leah leaves it with an 'I'll see you in court' kind of threat.
Do you guys think Corey has been dragging his heels on getting the insurance to approve the wheelchair or do you think Leah is being too pushy? Sound off in the comments below.
