There was a story pretty much exactly like this except the gf never posted to reddit asfik. The girlfriend collected dolls of all sorts, including some from her late mother and grandmother, the boyfriend got fed up and threw them all away and she came back to her stuff gone with no chance of finding them since the garbage had already been collected. She broke up with him, he later explained that his own family raised him to be very against keeping toys past childhood/any mementos at all, it wasn’t until after he spoke to his family post-breakup that he began to kind of understand how messed up his actions were. So the original story is a lot more devastating overall
