Believe in Me (Demi Lovato Fanfic)

You're My Only Shorty

Demi's POV

The next morning, I woke up to an adorable sleeping Lilly. I couldn't resist taking a picture (yeah I'm creepy, I get that a lot) and knew it was good blackmail (not that I'd ever put that out there hehe). I threw on some sweats and went downstairs to buy us some Starbucks. I wrote a note, jumped in the car and left. I couldn't help singing along when I heard Skyskraper come on the radio. (A/N I decided to make this a few months after Demi got out of treatment so her and Lilly were only a year apart). I went into the store and ordered two tall white chocolate mocha lattes. I paid and left to go home. 

When I opened the door, I went upstairs to wake up Lilly. To my surprise, she wasn't there. Suddenly, I heard talking from the bathroom. I went over to get her, but what I heard made me stop dead in my tracks.

"Hey girl, yeah she's not home right now."

A pause, than more talking.

"Yeah, she'll be back soon. Why don't you come around 3? I know she'll be at the studio then. Mhmmm. Okay. See you soon, I can't wait to see you!"

I stood in front of the door, blood boiling. I couldn't believe it; I leave for not even half an hour, and she decides to go and cheat?! Even worse, the morning after the first time we had sex? I couldn't believe it.

The door opened, and Lilly started to walk out. When she saw me, all the color drained from her face. "How much did you hear?" she whispered.

"All. Goodbye you cheater."

"Wait! Demi I can explain!"

"Explain what? How you were busy planning to get in some other girl's pants, while I decide to go surprise you with Starbucks?' I screamed.

"Demi...I...that..-"

"Stop. I'm going out for a while." I cut her off and spun around, slammed the door, and went to my car. I started bawling. I decided to call Marissa. She knew something was up as soon as she picked up.

"Dems, what's wrong?" she said with concern.

"Lilly fucking cheated on me. I just heard her talking with the whore on the phone. She was going to come over when I was at the studio today." I sobbed out.

"Demi, it's not what it looks like," Marissa said, clearly hiding something.

I hung up. I lost my trust of my two best friends today. I turned on the car and peeled out. I need some distractions.

Lilly's POV

When I woke up, Demi was gone. Ah, this is the perfect time to call Marissa! Demi is gonna be so suprised when she sees we're throwing her a huge 19th birthday party.

I went to the bathroom and called.

"Hey, you ready to plan the most kickass birthday party ever? Is Demi home?"

"Hey girl, yeah she's not home right now." I replied

"Okay great, will she be back soon? We can plan when she's gone.

"Yeah, she'll be back soon. Why don't you come around 3? I know she'll be at the studio then. Mhmmm. Okay. See you soon, I can't wait to see you!" I said.

"Okay bye!" Marissa responded. I hung up and opened the door. I felt my face turn white. Demi.

 "How much did you hear?" I whispered.

"All. Goodbye you cheater."

"Wait! Demi I can explain!"

"Explain what? How you were busy planning to get in some other girl's pants, while I decide to go surprise you with Starbucks?' she screamed.

"Demi...I...that..-"

"Stop. I'm going out for a while." she turned around and slammed the door. A few minutes later, I heard a car pull out. 

Great, now she thinks I'm cheating. Maybe I should've talked like she would've heard it. But no, here I am, fucking up our relationship again.

I decided to call Marissa again.

"We're in deep shit Lilly,"

"You think? Come over here and we can fix this and plan."

"Be there in 5."

A few minutes later, I heard a knock on the door. I opened it and Marissa looked incredibly upset. 

"Lilly, Demi thinks that you cheated on her with me."

"WHAT?!" My jaw dropped.

"Yeah, she thinks so. We have to fix this, even if it means ruining the party. Both of our relationships with her are way more important than some dumb party."

Demi's POV

I barely avoided crashing into about 5641654 cars because I was crying so hard. First I found out that Lilly was cheating, but with Marissa?! Marissa is supposed to be my best friend! She doesn't even like girls! Shit, I messed this one up. I made a u-turn and was on my way home when a neon light caught my eye. I cut across about 4 lanes of traffic and recieved many honks. Nonetheless, I made it to the parking lot. Hmm, I'm definitely coming here tonight. Nobody can know though. One night won't kill me. I got back in the car and went home. I couldn't wait till later.
