Relationship advice

H
My boyfriend broke up with me a week ago. We've been together for almost 3 years. I blame him and yell at him from stuff in the past and that is what tore us apart. He's not the best to me all the time but he cared and I know he does. Anyway I kicked him out of our apt in Houston he always threatens to go to Dallas. Well while I was at school he did. I called him before I left and told him not to leave he said we would talk about it after I got home. When I came home he was gone. He told me he was going in a trip with his friend to Chicago and he was going to give me space. We were still arguing and his parents told him to make a decision and stop going back and forth. We've been having this on again off again relationship but he always comes back. It always happens when it's time for us to move and this time he was graduating. I didn't answer his calls and he called me wanting to come back I asked for an apology and he got upset and said we fight too much and he was staying in Dallas and he made his mind up. I kept calling and begging him for a few days to come back because I miss him. He said it wasn't happening he loves me but not happening. I kept pushing and he got really mad at me and told me he was happier, healthier and less stressed with out me then he just flat out said he was better off with out me! Followed by " I'm not trying to be mean but u need to fuck off" I really love him and miss him . I was just emotional and wanted him to come back. Now it's been almost 4days and I haven't responded to his last texts they were pretty mean. Do you think he meant it or he just wanted space? I've also got a few calls from a private number when I answered last night they waited a little and then hung up. I feel like it's him. But it doesn't seem like he's coming back😞we have an apartment so he'll be back for move out at the end of the month. I'm just trying to do the no contact thing  but it's killing me! I miss him and it's only been like 2 weeks. I just want to show him I am serious about our relationship and I won't make the same mistakes I did before. I really love him. What should I do?
