Need to vent

So our baby is almost 9 weeks on Wednesday for the past couple of days he gets fussy at night. He cries so much and I nothing soothes him, he’s been really gassy. He sometimes cries when he farts. So yesterday my husband gets home and says let’s try giving him formula, I was only breastfeeding him. So I say ok and he’s like I just want to see if it makes a difference. Then at night he says if he does better tomorrow with formula then I should stop breastfeeding because he doesn’t want a fussy baby and it could be my breast milk. I feel bothered because I liked breastfeeding and I had just purchased breastfeeding shirts and bottles to be able to pump. Idk if I’m overreacting but it’s bothering me.
