Would you let your boyfriend keep the stuffs that were given by their ex? My bf is a sentimental one & he loves keeping stuffs that reminds him of certain events(he kept a rock that he took from a beach when we went together for the first time).

So my bf and his ex broke up 3 years ago, and he’s still keeping her stuff. Those are love letters, framed pictures, gifts, and tickets from when they went to the cinema together. She cheated on him and he broke up with her. I know he loves me very much, but its bothering me that he still keeps her stuff. According to him he likes to look at those things to remind him of the time they had together, and of a love he had when he was young and naive. The ex is still chasing after him after these years but he chose me instead, however i sensed that deep down he cares for her still.
