Husband doesn't have my back

First time mom here. I'm a stay at home mom since the baby was born. Being her mom is the best, but  I've been dealing with postpartum depression and anxiety on and off. My husband is made of stone, his feelings always stay in and I'm the complete opposite. I still struggle to this day, telling him how my day is going and what I struggle with and most the time he doesn't reply. He told me my feelings are a bit silly sometimes so he would rather not say anything. It's hard I feel like as my husband I should be able to talk to him, and he shouldn't make me feel worse.  Now I found out that he's been telling his friends how I struggle with motherhood. This hurts me so much. Day to day I try to be the best mom I can be.  I do the day to day on my own, this includes taking care of the baby and laundry, clean the house, taking his daughter to school every morning, having dinner ready, I sometimes even pack his prep meals for his diet plans. I'm tired. He hold the baby for maybe 10 minutes when he's home.
