Boyfriend keeps his ex-wife's wedding photos.

No need to ask, no one's heart is uncomfortable. Why can't you forget the old one when you have the new one? I think you can find a suitable time to talk to him and express your opinion, so as to avoid saying that he thinks you are narrow-minded and deliberately finds fault with him when quarreling in the future. I admire you, too, but since you have asked questions, you have a lot of pressure and grievances in your heart. This kind of thing should be said mildly, for example, if you say "Let's take a photo with him" and then post a photo of you and him on his mobile phone, if he is reasonable, he will clearly know your thoughts and feelings.
