I Feel Like He's Being Over dramatic

Me and my boyfriend had really bad fight and he might break up with me. See I'm an open person. There's no secrets with me. Everyone knows everything about me. Zero secrets. That's just who I am. Well my boyfriend doesn't like the dark (Don't even ask. I can't with him). She we have a nightlight in our room. I try not to be rude about it. I find it weird, but oh well. My friends were over to study for finals(our finals are online) and we were in our room. My boyfriend was trying to fix the door because it keeps coming off the hinges. They asked about the nightlight and I said Carsen's afraid of the dark. We all laughed together. Later that day he asked why I told them and he said he didn't appreciate that. I told him I'm blunt and honest. Then he starts yelling saying how I tell everyone his business. He brought up a situation that happened with my parents. Basically his relationship before me he had gotten a girl pregnant and they had an abortion. He got mad I told my parents. I personally don't see the problem. I'm an open person and he knows that. He said he won't tell me anything else and y said then our relationship won't work. I personally feel like he's being over dramatic.....
