The argument with Mattheo had been building for days, and now it had reached its boiling point. You both stood in your room, voices raised, the tension between the two of you is undeniable.

"I don't understand why you keep shutting me out, Mattheo!" you exclaim, your frustration evident.

"I'm not shutting you out," he snaps back, running a hand through his hair. "I'm just... dealing with things."

"Dealing with things? By ignoring me? By acting like I don't exist half the time?" you shoot, your voice shaking with emotion.

"It's not like that," he says, his tone defensive. "You wouldn't understand."

"Then make me understand, Mattheo! I'm tired of feeling like I'm in this relationship alone," you plead, desperation creeping into your voice.

"You don't get it! It's not that simple," he yells, his eyes flashing with anger.

"Then explain it to me! I'm right here, trying to be with you, but you keep pushing me away."

Mattheo looks at you, his expression torn between anger and something deeper. "You think this is easy for me? You think I don't have my own problems to deal with?"

"I know you do, but we're supposed to deal with them together. That's what a relationship is about," you say, your voice softening.

He lets out a bitter laugh. "Together? Half the time, it feels like we're just pretending."

"Mattheo, what are you saying?" you ask, your heart pounding in your chest.

"I'm saying..." he pauses, taking a deep breath before yelling, "I'm not happy with our relationship!"

You freeze, feeling like you'd been punched in the gut. The room falls silent, his words hanging in the air, heavy and painful.
