She's pretty much burned all her bridges with Matty (Beau Mirchoff), but Jenna (Ashley Rickards) could realize that taking a big step in her relationship with Luke (Evan Williams) because of it was a big mistake for her to make on Awkward.

Jenna will move in with Luke for the rest of her summer home, making a big step in her relationship, but she could soon find herself wondering if it was a wrong decision after the initial happy sheen of their living together wears off.

"Now that I was living with Luke, the days at IdeaBin dragged endlessly," she says in a preview clip for the Tuesday, May 10 episode. "I just wanted them to be over so I could get back to our blissful nights."

However, when she approaches Luke to make plans for that night in particular, she will be devastated when he informs her he has other arrangements for the evening, with Lizzy (Rachel Melvin).

"I have plans with Lizzy," he says, "She wants me to come with her for this book party."

"As her date?" Jenna asks.

"Of course not. I'm just her plus one," he replies.

"So I can't come," Jenna notes.

"I wish, but it's not plus two babe," he says. "Besides, if you were there, our cover would be blown because I couldn't keep my hands off you."

It is then that Jenna remembers that without Luke heading home, she's stranded, and when he offers her no solution and leaves with Lizzy instead, she will begin to rethink her entire plan of living with him, wondering if she made the wrong move instead of the right one.

"Moving in with Luke was supposed to be an adult move," she wonders in the clip. "But suddenly it was feeling like the wrong move."

Awkward airs Tuesdays at 10 p.m. on MTV.
