Heartbreak

So about 9 months ago I found out my boyfriend cheated on me. I forgave him but I didn’t trust him again. It was still fresh to me. Last night he kept asking me what was wrong saying he could read it all over my face. I honestly had nothing wrong with me. After asking me a million times I caught a little attitude and turned over to my side on the bed and fell asleep. Before he left for work he didn’t kiss me and say I love you like he normally does. Instead he just said bye. Then I text him saying that was rude of him to do and it started a fight. Now we are broken up and we’ve been together for 3 years. We have been on and off and fighting constantly. I love him so much and I don’t want to lose him but I don’t know what to do to fix this. He saids he’s done and doesn’t want to be with me anymore. He saids this every time we fight and a couple days later we make up. But I feel like this time he’s really done with me. My heart is breaking and I can’t stop crying. We live together and sleep in the same bed. Any advice please.
