Prompt: Regina's heart was destroyed facing Zelena (somehow), Robin makes Gold put half of his into Regina, then Marian comes back ... how can he love Marian when literally Regina has the other half of his heart now?

She reached into her chest and pulled her heart out, the half he had given her of his own heart after Zelena had crushed hers, and stared down at it, wondering for a brief second if he might feel it too if she would just crush it.

Her fingers closed around it and she felt pain shooting through her but no matter how much she wished the pain and hurt would just stop she couldn't do it. Because of Henry ... and because of him.

She still loved him. She couldn't just lock it away. She had opened up to him and having his heart inside of her had just made it that more intense but now it only caused her almost unbearable pain.

She could feel what he was feeling and it was driving her insane. She had felt his overwhelming joy as he had seen Marian again and she had fled out of the diner, rushing back home but when she had been lying in her bed later, a wave of hurt and anger had washed over her and she had needed a few seconds until she realized that it wasn't what she was feeling but what he was feeling and she had buried her face in the pillow, sobs racking her body as she mourned the loss of the love of her life.

It had to stop.

Turning around, she lifted the lid from the small chest in front of her, laying the heart into it softly, closing the lid firmly. She would store it at a safe place because she couldn't live with it being in her chest anymore.

A knock on the door startled her and she furrowed her brows, throwing a glance at the clock. Henry was staying the night with Emma and she was not expecting any visitors.

She crossed the hallway quickly, opening the door, her mouth already open to tell whoever was on the other side that they should just leave her alone but when her eyes fell on the person standing on her porch she couldn't utter one word.

"Regina?" He was soaking wet, the hair was plastered against his head, his whole body shaking as he leaned his hands against the doorframe, his voice barely audible as he rasped. "Please let me in. I need to talk to you."

She wanted to slam the door into his face. She wanted to yell at him to just leave her alone because she couldn't look at him without the realization what she had lost almost suffocating her.

But she couldn't do it. Even without his heart in her chest she could still almost feel his pain, saw it written all over his face and she still loved him too much to push him away so she opened the door wider and let him in.

He was standing at the fireplace as she entered the room, staring into the fire, his wet clothes steaming in the heat, his head resting on his forearm and a jolt of pain rushed through her as her eyes fell on his tattoo.

"Can you please take it out?" She almost didn't hear him as he spoke so lowly that his voice was nearly drowned out by the crackling of the fire.

"What do you mean?"

He turned around before he answered her, the anguish in his eyes knocking the breath out of her.

"I can't bear it any longer. It's too much. I'm ... I'm feeling too much, Regina. It needs to stop. Please take it out."

She was staring at him, unable to move, her mouth forming words before she could stop them, hope rising up in her chest, hope she shouldn't feel. "Feeling too much?"

He took a step forward, stopping dead in his tracks as she flinched away and he gulped hard, tracing his hand through his hair, making it stand up in all directions and her fingers itched as she wanted nothing more than to walk over to him and smooth them down.

"For you." His voice was hoarse with emotion, his eyes pleading with her silently to understand. "God, Regina. I love you. But I can't ... we can't. I have a son. She is the mother of my son and I ... we ... but ..."

He trailed off and a shudder ran down her spine as he looked up at her again, his eyes shimmering with unshed tears. "But I love you, Regina. God, I am so in love with you that I want to rip my heart out and crush it because I can't take it any longer. I can't live like that."

He stumbled backwards, almost falling into the fire and without thinking about it she was by his side, wrapping her arm around him, steadying him and a moment later she was pressed against his chest, his arms crushing her against his body.

"I love you."

Tears spilled over and running down her cheeks as he repeated the words over and over again, his hands suddenly pushing her away just to crush his mouth on hers a second later, his kiss being hungry, passionate and possessive.

She didn't know how they ended up on the couch, how much time had passed since he had knocked at the door.

"I missed you." He rasped against her forehead, his hand trailing up and down her spine, his fingers entwined with hers. "I missed you so much."

"Robin?" She leaned back, not wanting to disturb the moment but knowing that she had to. "You have to choose. I'm not going to be some dirty affair. I want all or nothing."

He lifted his hand, his thumb brushing over her cheek as he cupped her face, a small smile tilting up his mouth as he breathed. "I'm choosing you."

She exhaled a long breath, relief washing over her and he pulled her back against his chest, murmuring into her hair. "This is a complete mess and I'm gonna hurt people that I love but I can't live without you. I just can't, Regina."

"And I can't live without you." Regina whispered, pressing a kiss against his skin. "I love you, Robin."

"We will be together, Regina. I promise you we will."

"I know."
