Trouble with hating a Riddle (Mattheo Riddle fanfic)

Truth or dare

Bree's POV
"You're still wearing it."
"What?" I ask looking up from my book to see Arya. She nods to the necklace Mattheo gave me the day before the break up. It's been a week. A very hard week. I look down and take a small breath.
"Oh, uh, yeah. I'm still wearing." I say, she smiles a little.
"You still have hope for you two." Aura says, I nod and she sighs. He light pink lips part.
"You know, I've known him since I was six and I've never seen him look at someone the way he looks at you. He has never smiled when he sees someone. He really loved you." She says. I look at her. She gets up.
"I'll leave you alone, you have homework." And with that she was gone. "He really loved you."
I sigh and grab my books and headed to the common room. I know she meant well with the whole speech thing, but the only thing that stuck was the loved. Does he not love me anymore?

Later
I bump into someone in the halls, I mumble a sorry and start on my way again. I feel an arm slam me into the wall. I glare at him. He smirks. Liam.
"I told you he wouldn't want you for long." I glance around to see nobody watching him. I shake my head. "No your wrong..." I try to push off of him. He raises an eye brow.
"Really then why was...never mind. That's not my business." He smirks evilly. He starts to walk, I grab his arm.
"What do you-"
"Hmmm." He looks down, into my eyes. "Arya, right? You know her? She" He asks, raise a brow.
"What does Arya have to do with anything? And yes, she's my friend."
"What a friend then because she and Mattheo were kinda making out earlier, the big tree outside. Really. He's done with you, Bree. Forget about it. No one loves you." He walks off, I stare at the window. Sliding off the cold corridor brick walls. I sit on the floor, hugging my knees, in a ball. I try not to cry. I watch as Mattheo and Arya laugh, walking together to the common room. Mattheo stops for a second and kept walking. Audrey sees me on the floor and sits next to me.
"Babe, What's wrong?" She asks, I shake my head.
"Arya...she and Mattheo...they,um, kinda made out..." I gulp. Audrey sighs, her head leaning back into the cold brick wall. I let my head fall into her shoulder. We stay like this for a while then head back to the common room.

Common room

Draco, Blaise, Tom, Arya, Pansy, Liam and of course Mattheo were all sitting on the couches when we walk in. We haven't all properly hung out since a week ago. Until, apparently, now. I don't know why the heck Liam is there but, honestly, I don't care. Arya laughs at something Mattheo said to her. Making me want to go upstairs to my dorm. But I'm done hiding. Audrey rolls her eyes and nods to a chair. I nod and head over, she sits on it while I sit on the arm. The room quiets down, we haven't all sat in a room all together optionally.
"Sooo..." Draco says, "anyone up for Truth or Dare?"
"I'm in." I say, making everyone stare. "What I wanna live a little, geez." I roll my eyes, Audrey smiles.
"If my baes in, count me in."
"Same" Pansy agrees, along with everyone else.
"Alright, Tom Truth or Dare?" Blaise says.
"Dare." He replies, Blaise looks around the room and smirks.
"Sorry, Bree."
"What-"
"Give your brother's ex a hickey." I glare at Blaise, he mouths 'sorry' to me. I roll my eyes. I don't even glance in Mattheo's direction.
"Come on, lover boy." I say, Arya raises an eyebrow but I ignore her. Tom sighs loudly.
"A dares a dare," he says, walking over to me. He looks over at his brother, "sorry bro." Then, putting his attention on me, he leans close to my neck and kisses it.

Mattheo's POV
I don't know what to do, so I just stare. How could she be ok with this? That should be me, not my fucking brother. Liam snickers, I keep my eyes glued on my brother sucking on my ex girlfriend's neck. This can't be happening.

Bree's POV
Tom stops and walks away, Mattheo death glaring him the whole way to his seat. I don't care. He ended things, made out with Arya, and he's mad because his brother was dare to give me a hickey? This boy doesn't make sense. Liam clears his throat, trying to make the tension go away.
"Bree, Truth or Dare?" I think for a second, putting my hand on Audrey's left shoulder.
"Dare." Liam looks like he's thinking and smirks.
"I dare you...to...sit on Draco's lap." I stare at him.
"...ok, I guess.." I get up from the dark green chair arm and walk over to Draco. I sit on his lap. His mouth goes close to my ear.
"This feels wrong." He whispers, I nod in agreement.
"Mattheo, t or d?" Audrey says, I glare at her.
"Uhh, d." He responds. Liam smirks, his arm resting in his knee.
"I dare you to-"
"Make out with Arya....again." Liam butts in.
Everyone looks between Mattheo, Liam, and Arya.
"No, I never made out with her in the first place." Liam laughs, glancing at me.
"You a pussy?" Mattheo shakes his head, his hands into fists. He rolls his eyes. And walks towards Arya. She stands and his hand wraps around her neck, softly. She whispers something to him, but no one could hear her. He slowly leans down and kisses her. It turns aggressive after a minute. My eyes glued to them making out. I rip my eyes away from him, connecting eyes with Liam, who was watching me. I turn around.
"I gotta go." I whisper into Draco's ear before getting off his lap and running to my dorm.
