wasted milk

So I don't produce much milk to have to pump all the time but when I do I'll have maybe 7 or 8 ounces to store. Every time I do have it I tell my SO to make sure he doesn't waste it or let it go bad... and every time it gets wasted and goes bad. I get mad at him and he thinks it's not that big of a deal I can just pump again.... I consider this milk liquid gold lol I barely produce enough as is and he says "just make more" 😑 lawd help me
