I'm worried this isn't going to work out

My bf and I have been together for two months now. We have never had problems until 3 weeks ago, now all we do is fight, about everything. If I say something or I don't understand something, and ask him to repeat it. He snaps and loses it, and then we start fighting. We've had fought about everything and we don't see eye to eye on small things but agree on big things. I'm not sure why we are even fighting but I'm a woman who use to get abused. I knw he won't hit me but my head is so big that when he's angry and I don't answer right away, that he will do it. I jus feel like I can't talk to him without sounding like an idiot. Someone please help.
