Husband mocking me for struggling with supply dip 3 months PP

Im a SAHM and I know it’s a huge privilege. My baby just turned three months a week ago and up until now I’ve been doing fine mentally. Something has shifted in the last two weeks and I’m feeling incredibly anxious, depressed, aggressive and vulnerable. My milk supply has also dropped by out 2-4oz a day and my baby is eating less frequently but always crying to be held so I literally have no opportunity to power pump. After I went to work with my husband today (family business) we got home and I breastfed but afterwards I could tell my baby was still not satisfied. I asked my husband to give her a bottle of formula and he mocked me while giving her the bottle saying “she’s so hungry” “mommy didn’t have enough for you huh?” WTF. I let it slide and bit my tongue. I told him that I believe my sleep deprivation is contributing to the drop in supply as I do ALL nights by myself. My husband sleeps in another room every night even when he’s off of work. Then I tried to lay down with my baby to get some sleep but she just wants to suckle and I cannot sleep with her latched. So I asked my husband to offer her some more formula and take her so I can rest and he says to my daughter while giving her the bottle “Mommy is angry at you” “Mommy can’t make enough milk for you so she’s mad.” WTFFFFFF. I started bawling. I let him walk out with her so I could compose myself then went and snatched her from him. I feel soooo unseen, so small, so used, so invalidated, so lonely… I haven’t slept more than 2 hours straight in weeks . Ive had no problem breastfeeding until last week. Any advice or solidarity is welcomed.
