Broke up!!!!!

Well my H and I broke up. It's over, and I am beyond upset, I don't know what to do where to go, nothing. I feel so lost.
We have been bickering lately and getting on each other nerves but last night it came to an end. We were at my sisters, who was doing her very first holiday and first holiday in her new house, where she was so excited. During dinner he mentioned she has a TV in her kitchen and said so we have to have one, I said no because when i was little dinner time was family time to talk and be with each other and i dont want a TV. Then he said something to my mother like did you have a tv in the kitchen, she said we did but got rid of it when I was 3. We were literally talking calmly, no yelling nothing.
My mother says this he turns to me screaming, in front of my entire family. 'B*o* Me! and goes on this rant how I better think before I speak and never saying never to him, and blah blah blah. Then he tells my mother not to write anymore checks for our wedding because he knew that we were not going to see DEcember. saying how he feels like he wants to cheat on me blah blah blah.
I sat there and was in dead shock. I wanted to kill him, I wanted to scream get out, but I didn't want to continue the scene.
After this we continued dinner calmly and tried to have regular dinner talk. After dinner he went into another room and my mother and sister began to ask questions, what is going on, is this true, is there going to be a wedding and such. My mother started to cry because she did not want us to break up, my sister kept saying i know you guys are going to make up.
Extremely long story short, he left before me and i was talking with my sister bother in law and mom and they were just going everything he said again.
When I left I had lots of missed calls, called him when I got home where he began to scream at me that i better answer when he calls and what a b*&?h i am finally i said i can't do this anymore, and he said he could not either and was just staying with me these past 5 months b.c he didn't want to hurt me, but now he has had enough and can't continue to want to marry me.
He called me earlier today and i thought maybe he wanted to talk, all he wanted to know is if I called and cancelled our hall, photographer church and stuff. I havent done anything like that I am way to depressed and think that this may just be a fight, he on the other hand is certain its done. I am so upset, don'tknow what to do. I haven't told anyone but my mother and sister about this they are supportive but upset.
I feel lost, I don't know what to do. I feel sick over this and so alone.
