I’m so mad!

So I just got done making dinner and I made my 3y olds plate went to make mine to sit and eat because I’m starving well my 8 year old and SO get home so before sitting down I made my 8y olds plate then my SO calls me to the room to show me what he had bought at the store. I was already in a rush to just sit and eat because I’m hungry and I haven’t ate since breakfast, well I went and see & then went to sit and eat and he comes in the kitchen and ask where’s his plate I look at him like he stupid because I ain’t the type to just make his plate I hate when he feels entitled well he then says so you can make everyone else plate but not mine and I said well they’re my kids and your grown you can make your own! And he’s behind my back mocking me in front of the kids. I sit down to eat and I asked him to pass me something off the counter and he tells me “No your grown, you get it, also your grown you can pay your car note and pay all the other bills too”. Mind you I’m a SAHM I have a weekend job for groceries and stuff but he’s always throws it it my face that I don’t make any money. I said I can definitely provide for myself, your mom done it being a single parent to 4 & getting on her feet. He said “well remember my moms one of a kind, all your gonna do is go live with your mom, you can’t provide.” I’m feeling so hurt after this I’m like I can’t live here anymore and my 8 year old looks at me and says “well if you move I’m staying here with dad, Maybe.” I’m so upset and mad. He comes to me after Im done eating, saying at first he was playing & I don’t have a reason to be mad and he’s blaming it on my pregnancy like he just didn’t disrespect me because I didn’t make his plate.
