What Should I Do With My Ex Boyfriends' Gifts?

So I came across this huge box which is filled with jewelry, letters, teddy bears/stuffed animals, pictures, and other assorted mementos from the dates that I went on when I was with them. I have decided to keep the jewelry since each piece has diamonds in it and I am not throwing away diamonds. The letters, pictures, and mementos from the dates have been made into a memory binder. I did this in part to keep the memories and also to show my future children that just because a boyfriend seems sweet and showers you with gifts does not mean that they aren't overly clingy and/or controlling (because that was exactly what my exes were). However, I have a ton of stuffed animals from my exes and I don't know what to do with them, there are so many of them and some of them are big. I was thinking of just keeping them in a box and storing them in the basement, I just don't have the heart to throw them out, they are my memories, and also in the future I can give them to my kids to play with so that they don't go to waste as clutter. What do you think? Would you be mad if you found out your girlfriend was doing this? Would you allow your wife to give her exes' stuffed animals to your kids?
