Trouble with hating a Riddle (Mattheo Riddle fanfic)

Jealousy

Mattheo's POV
My brother made me go to this party. Usually I would be glad to go to a party. But today's different. I stand by the drinks, taking a sip of my third drink this night. I hear a familiar voice and turn a little. Holy shit she's gorgeous.

Bree pov
I walk in the room, holding hands with Audrey in my tight, light blue sparkly dress. I look hot I know that for a fact. I could feel Mattheo's eyes on me but I ignore them. Pansy walks up to us smiling, and hands us each a drink. I nod at her and take a sip it.
"Holy shit your hot." Pansy states, I laugh.
"I know" I smile, Audrey smirks.
"Let's go danceeee" Audrey says, pulling me to the dance floor. Pansy laughs.
"Have fun you two." She says.
"No your coming to, come on." I say, taking pansy's hand while Audrey pulls me away. Pansy laughs.
"Oh my god."

After a while of dancing I felt hands at my hips and I turn to become face to face with Potter.
"Well hello" I say, smiling. "Didn't actually think you'd-"
"Shh" He says, nodding to the drink area. I glance over to see Mattheo staring right at us bringing a red cup to his lips, obviously pissed. I look back at Harry and smirk. I start to grind on him, and slowly move my hands on his chest to his neck then to his hair.

After a while I got tired and told Harry I'm getting a drink. When I walk up and poured myself some alcohol in a red cup.
"Enjoying yourself?" I turn to see Mattheo, who hasn't moved from his spot. I roll my eyes.
"Mmhm sure am." I say taking a drink out of the cup. Mattheo looks at me. Then sighs and says, "Harry seems to be enjoying you too." I almost cough out my drink. He smirks at me and walks away. I see Audrey and walk over to her and start dancing with her.

"Ayyyyyee! Who is you for never have you ever?" Some people 'woo!' And others just walk over to Blaise. It's the end of the party mostly everyone is gone. I sit on an arm of a seat, while Harry sits in the seat and Audrey sits on the floor, and Pansy sits across the room. I look around the room and I see Mattheo start walking over to the group with the same girl as before who he was flirting with.
"Okkk, lets start, shall we?" He glances around the room. "Ummm. Oh I got one." He settles into the couch he's sitting on. "Never have I ever kissed my best friend or a friend." I chuckle a little bit looking at Audrey then Pansy, taking a drink. Mattheo raises an eyebrow but says nothing. Harry laughs.
"We all shoulda known about that-" I laugh, looking down at potter.
"Mmm ok. Never have I ever..."
"Oh oh! Never have I ever had sex with someone in the room!" A girl I don't know says.  I slowly lift the cup to my lips as does Mattheo. Awkward. I feel a hand on my thigh, I look down to see Harry's hand there. I glance up to see Mattheo's cup practically squeezed shut.
"Ok...um, never have I ever stolen something." I laugh and again put the cup to my lips. Harry looks at me.
"You stole something?" He asks. I smile, looking down at him.
"Sure have, pretty boy. You haven't?" He gulps.
"No." I laugh.
"Kinda figured." I replied, Audrey smiles at me.
"Never have I ever made out with a guys girlfriend in front of him cause he was cheating on her."
"Damn. Your going after me aren't you?" I ask looking at my best friend. She shrugs, smiling.
I sip my drink.
"Your pretty badass, Bree" Harry says.
"Why thank you, Potter." I smile and kiss him on the lips. When I pull back he looks surprised but glances at Mattheo and smiles.

Mattheo's POV
Fuck. She's moving on fast. And not only that but with Potter. After the party, he left and was quietly walking to his common room. I followed him and smashed him in the wall.
"What the fuck, dude?"
"Don't go near Bree."
"You broke up with her, she's not yours anymore. She is a single lady who can do what she pleases." I glare at him. But I know he's right.
"Besides I'm not the one flirting with girls right after you broke up with her. Not to mention making out with one of her friends in front of her, I mean I get it it's a dare but still."
"Shut up."
"And plus, she loved you and you just threw her away. She was willing to do whatever for you. Even when she knew who your dad is."
"Shut up."
"And I know for a fact that a lot of guys want to fuck her-"
"SHUT UP!" I yell before I punch him in the gut. Right when Bree walks out great.
"WHAT THE HELL MATTHEO!" She runs over and pushes me off of him.
"You ok?" She asks that piece of shit. He nods.
"What are you doing? Are you serious right now, Mattheo? Really?" She asks, I just stare at her. "Go Harry. It's fine-I'll be fine." He silently nods and quickly walks away. When he's gone. She groans and walks in a circle.
"Seriously? Are you serious right now-" I cut her off by kissing her. She kisses me back, which I was shocked by. Then she realized what she's doing and pushes me off.
"What the fuck, Mattheo!" She screams, meaning Audrey and Pansy are going to be out here any minute. I run my fingers through my hair.
"Sorry-sorry." I sigh, "I just-I love you." She stares at me for a second then laughs.
"You broke up with me then now your saying you love me? Is this a joke? Am I some type of joke to you?"
"No,no-I" she runs her hands through her hair then places her hands on her hips.
"If you love me..prove it." She says. I don't say anything. I just kneel. Which when riddles kneel it's only to their one and only.
