<human>: Last Friday night my boyfriend invited me to dinner with a bunch of his family members. We've been together since August 2012. We went to a nice restaurant and everything was going fine and until he started giving a speech on how much he loved me, wanted to spend the rest of his life with me, etc. Before I knew it he was on one knee asking me to marry him. I've told him more than once that I never ever ever want to get married. I don't want to be someone's wife and I don't want a husband. Anyway, after he proposed I was in shock for a couple seconds. I didn't say anything for a while, and I didn't mean to but I laughed and straight up said no. I laugh in awkward situations so I made it even weirder. Soon as I said no his face dropped. He left the restaurant for a few minutes (his mother followed him out) while I sat there awkwardly with his family. Thankfully none of them asked me why I didn't say yes. When he came back inside we finished an extremely awkward dinner, my boyfriend and I live together so after we paid we drove back home. 

Soon as we got home we got into a fight. He yelled at me and said that I embarrassed him in front of his family and called me selfish. I reminded him I said I never wanna get married but he said he thought it'd be different with him.

 He's at his parent's house and has been since Saturday morning. I've tried calling but he's ignoring me. I spoke to his brother this morning and he said my boyfriend was considering a break up and that I should get ready to move out. His whole family pretty much hate me now. 

What can I do to convince him to not break up? We've been so happy for so many years and I don't want to lose him over this. We can be together without being married.

Give me the gist of the text in a nutshell
<bot>: My boyfriend proposed, I said no, he wants to break up but I still very much love him and want to be together. What should I do?
