Q&A Should I Ask about All the Media and Locations They Shared?

We are 5 months past D-Day of a 1-year-long, type 2 affair. I have discovered some difficult information about locations and songs that were special to me or us, that he shared with the affair partner. Should I ask for a comprehensive list of songs, movies, shows and locations he shared with her? Anything else I'm not thinking of? And once I have the list, what should I do with that? Reclaim them by sharing them with him now? All of them or just the ones that are important to me? Do I risk anything doing this? Would this trigger affection in him to the affair partner, for example? Or would it build resentment in him that I'm trying to reclaim this stuff? There is a question between us about a city he took her to. I had read a text where he told her "he would never go there with anyone else." I want him to take me to that city and thus break that promise to her. He says it would just be painful for him to go there now knowing he had been unfaithful there. I am very aware this may sound very juvenile and petty, but I also don't want him to hold on to anything special from this relationship, no sacred strongholds.
