BF is mad at me 😒

I am spending the weekend with him. We both worked today, he got off an hour earlier than me.

He went to the store and got some snacks and frozen pizzas and stuff for me to eat bc he never has anything to eat, and when I bring food from my place (because I know he never has anything), I leave it at his house and next time I come back it is all gone.

We were laying in bed watching tv. We both went to the kitchen. He grabbed my prenatal supplement fiber + calcium chewables. I have asked him not to eat my vitamins because he will freaken eat all of them and then I have to go buy more and hello I'm growing HIS child wtf. Like it's fine if he eats my shit I GUESS but my prenatals? Really?? And so he ate one while we were in the kitchen and I noticed there were literally only three left. I got annoyed and I went back to the room after telling him that it's rude to eat all of my vitamins and not replace them.

There's been a couple other things that are causing us to be immature right now and cold shoulder each other but I'm curious if anyone has advice or insight about the vitamin thing. Idk if I'm being irrational but it's like ok you eat them and they're to grow your baby and then. I have to take my round ass to the store to get more??? I think it's rude..

I mentioned all the back story about going to the store to show that he does do sweet things for me.. not sure if that changes anything
