Husband threw away my breastmilk

I had a deep freezer completely full of breastmilk and my husband threw away 90% of it, if not more. I’m so upset and frustrated I feel like I could cry. My husband doesn’t get why I’m upset because I “wasn’t using it” so I feel kind of silly feeling this way but either way I can’t help but feel sad about it, our baby is less than a year old so I have plenty of time to have used it. I put so much time and work into getting the milk and filling the freezer and am so paranoid about my milk supply suddenly falling one day and now I barely have any milk saved if it does and now that baby eats more I can’t really save milk anymore and was getting close to having to use the frozen stash of milk.
