I think it's about a lover being abusive. "Two hearts beating one beats the other" he's mean to her but she just looks away from it saying 'he won't do it again' "the problems all a shade of gray" it's still hidden, the problem is staying in the shadows. "Erasing these two photograph are just a waste if your time." She sees him in the photographs and tries to forget and erase the real problem. Looking in these photos he looks nice. She wants him to stay that way and fears the worst if she tells anyone.
Really complicated me at first but I think I know it now.
