Husband doesn't treat breast milk like gold

I'm probably just paranoid but I feel like my husband doesn't understand how important breast milk is. I'm a FTM who EBF. I'm trying to build up a supply before I go back to work since pumping at work will be a challenge.

He is kind and let's me sleep and will use my stored milk to feed baby but often times he wastes a bag heating it up just so it will be ready for her and leaves it out just to be thrown away.

Also if I don't pump enough for a full milk bag he will just dump the 2oz down the sink saying it's not enough to be worth trying to save.

My baby is 6 weeks old and I've filled about 70 bags with 4-5oz each. I go to my kitchen and see a full bag of milk defrosted that has been left unused for hours and seeing that I only have about 20 bags left in the freezer now just breaks my heart.

Am I getting myself worked up over nothing? Or do I have a right to feel devastated? Any advice to explain to him the importance of every ounce?
