Hello, I’m new here

I’m new here and not really sure where to start. I’m facing a challenge with my bf and I. We have been fighting a lot and not communicating really well. He yells at me because to him I’m a brat and I don’t know how to do anything right. I do a lot not just for him or me but for the house itself. I clean, cook, make sure his uniform is ready in the morning. I’m not complaining but anything I do or say causes a fight. He says my tone is annoying/whining and he doesn’t want to hear it. We use to be happy all the time, we hardly ever fought and if we did we talked through it but now it’s different and difficult for me to understand what I should do. He says I can fix it if I just stop asking dumb questions, if I just listened, If I just did things correctly. I feel stuck because I don’t know what I need to do. I do know I don’t want to lose him.
