Teen Mom’s Leah Defends Decision to Move In With Corey

That was fast!

Though their relationship is now on solid ground, Teen Mom 2's Leah Simms was forced to provide her family with answers after deciding to move in with boyfriend Corey two weeks after a post-split reunion.

"What makes you think you can make this work?" Leah's mom asks her daughter — who reunited with Corey, 20, after a dalliance with an ex — in a sneak preview of Tuesday's episode. (Watch a preview above)

So why complicate things when the young parents — now married — are already dealing with daughter Ali's developmental health issues?

"We're both ready [to live together]," 18-year-old Leah says in the clip. "This time, he's not the only one in it, I'm in it too."

And the teen mom is ready and willing to mend her relationship quickly — for her daughters' sake.

"It's kind of hard to take it slow when you have two kids," she reasons.

Teen Mom 2 airs Tuesday at 10 p.m. (EST) on MTV.
