This guy I have been seeing for the past month recently broke up with his girlfriend of almost three years. I understand that they were together a long time and that they were in love, but I have a few minor concerns. On his ex's Facebook profile, she had a profile picture of him and her as well as a cover photo of the two of them together. The day after they broke up she changed her pictures but he has yet to change his. I also know that he keeps a picture of her in his wallet and multiple pictures of his phone. I'm not worried or anything about it but I want to bring it up to him just to see what he says without him getting mad. How should I go about this?
