Regina had gathered a lot of photos in her time as a parent. Most were of Henry when he was a baby. She didn't really have much of him now, considering he always begged Emma to be in them, but Regina didn't want her to be. There was a time when Ms. Swan was in all of her pictures; there were even some with both her and Regina, arms wrapped around waists, loving each other's company. But the blonde knew, just as well as the mayor did, that those days were over, no matter how badly they wanted to get back to where they were before.
Things between them had ended in a rather unwelcome way. Emma was stuck between Regina and Graham, sometimes lying to one of them just so she could see them both in one night. She couldn't believe she fell for any of the lies the sheriff was giving her, but this was the first time she was in love since Daniel and she just didn't want to believe everything was going down the tubes.
This is why she never put her heart fully into anything, besides Henry. He was with Regina when Emma annouced she was choosing Graham. Regina thought he'd run off with the blonde and leave her to grieve all on her own, but he didn't; she was his mother, too, and he knew that she needed comfort more than Emma needed a kid trailing her to her new home. Henry had helped her do things around the house and even cleaned his room when she told him to. When she was having one of her off days (mostly after seeing Emma and Graham being lovey-dovey at Granny's, or just in general) Henry would walk up to her and just hug her as tight as he could, wishing he could make all of the pain go away.
Regina had caught herself daydreaming about what could've been had they stayed together, the stack full of Henry's baby pictures slowly falling out of her hands and onto the floor. She had been snapped back into reality, gathering the fallen items back up as quickly as she could, shoving them all back into the box they came from. She stood up, ready to put the photo box back into the closet where it belonged, but she stopped, reaching out and running her fingers over another box, the ones with all of the memories of Emma.
She set one box back where it was supposed to be, but she grabbed the other before closing the closet door. Regina knew it would be a bad idea to live their relationship all over again; she couldn't stop, she didn't want to.
As she pulled out each individual picture, smiling faintly at all of the goofy faces the sheriff would make when the camera was pulled out; she couldn't help but wonder what it was like to actually be with someone til death. She had dreamed about that her whole life, but she knew there was no way she was ever going to know for sure. Regina was certian she didn't ever want to love again.
