Moved in together, sorting through our clobber. My DP has a box of old correspondence which includes quite a lot of letters from an ex, this relationship ended more than 20 years ago (when people still wrote to eachother 😀). I have also had letters like this but got rid of them along the way as I couldn't see any value in holding onto them. I haven't said anything but I feel odd about the fact that he's held onto them, she's definitely not the one that got away and to some extent it's more to do with the fact he is a hoarder and this is the first time he's moved in decades. He has yet to 'sort' this box but in the meantime I'm feeling stressed incase they stay in there. If so, how do I even approach this with him? He doesn't know I know they exist.
