Ensuring a healthy pregnancy typically requires that you have a stable and positive living environment, but not all of the girls we see on "16 and Pregnant" have access to that. Next week, we'll meet expecting teen Allie, who unfortunately is left with no choice but to live with her boyfriend, Joey, and his verbally abusive mother.
Check out this sneak peek of Tuesday's "16 and Pregnant" season finale, where a destructive fight is instigated over Allie tossing a banana. Joey's mom lashes out by saying that Allie's own parents didn't want her and even threatens to hurt her physically.
