Crying over spilled milk

I’m a first time mom, 8 months postpartum. Just wanted to ask you guys if its okay to feed your baby chilled milk?

Back story: crazy how 1 simple thing can change your perspective in life. It’s my FIRST mother’s day (a very unforgettable one indeed) and I had a big fight with the baby daddy cause of COLD milk. It was 1 in the morning I was half asleep and my baby cried cause he was teething so bad, I comforted him while I was doing all the carrying and hushing the baby daddy told me to get him some milk, I wasn’t able to heat it up cause he was crying so bad then he got so mad cause I did “shortcuts” He repeatedly called me stupid, and unwilling to learn all because of this. He yelled at me, reminded me of ALL my mistakes I have done and even provoked me so much I got so triggered, I wanted him out of my sight, I let him sleep outside before we say more hurtful words to each other.

I’ve never felt so little, my only focus was to be a good mom to my baby and to top it off he even forgot about Mother’s Day for me (there goes my first celebration). I know I make mistakes maybe I do suck as a mom…. But was this too much? 😔
