Depression and an unsupportive bf

I feel so alone right now. I’m at home with my 18 month old and now 8 year old bc school is cancelled. I’m 31 weeks pregnant and my bf says I’m delusional bc I don’t see that I’m always giving him attitude. I just answer his question and it’s apparently not the way I’m supposed to answer his question or as he says it’s not what I say but how I say it. I tell him it’s not intended that way and he tells me it doesn’t matter bc it’s how it sounds. He says I walk around with resting bitch face and starts laying into me about not respecting him. So I start crying and getting really upset bc I am not intending it in anyway with attitude. So I feel confused and question myself. When I start crying he starts being really mean and tells me he has no respect for me for crying in front of the kids but I just feel like I’m crazy and i can’t control the crying or trying to defend myself. It’s pushed me into a depression and I’m starting to hate myself for it. I feel like maybe I’m wrong and it makes me hate that I can’t change something I don’t mean to do and I hate myself for crying in front of my kids but I literally can’t help it when he gets mad at me. Sorry for the long venting post but I just feel like all I am is a mom and gf and I’m failing at both. It genuinely makes me hate myself. I do t know why I’m posting here other than I just feel alone and hope someone somewhere can help me make sense of everything.
