He needed to tell her. She obviously knew he loved her, but he needed to confirm that. He just didn't understand why it had to be so hard. All he wanted to say was three simple words. If he didn't tell her soon, she would go on that trip and he would never be able to tell her. That would be something that he would regret forever.
He hadn't told Rose his feelings either. Though he had moved on, he still felt guilty for trapping her in a parallel universe. He hoped she was happy with the half-human Doctor.
He grabbed a bowl and poured some broth into it. River was who he loved now, and he cared about her. He felt bad that he couldn't always be with her, that she had to be stuck in that prison because of him.
Chicken was put in the bowl then. He would not make any of the mistakes he had made before ever again. He'd been the hurting the ones he loved by doing so. Gosh, he had ruined a huge part of Amy's life with Rory. He couldn't let River's life get any more incomplete. Not because of him, not because of anyone.
He threw in random vegetables next- celery, broccoli, carrots, cucumbers, zucchini- anything he could find. She was his wife, he loved her. And he would protect her. Today was the day he would tell her.
