How do I convince him to understand me?

I am meeting up with my ex tonight and we were and our way to getting back together then yesterday I kinda created an arguement and he just flipped at me and told me he never wanted to speak to me again and that I was to stay out his life and he wants a new girlfriend and I got him to meet me tonight by tellingh him if he sees me and tell me face to face it is over then I should be able to leave him alone… I only said that to get him to see me… my best friend and most my other friends keep telling me he wouldnt really get rid of me but I dont know how I am going to convince him to listen to me as he keeps saying he doesnt care about me… all because of something that wasnt my fault. he said that I lied about changing and he knew I wouldnt but I have changed and I went through emotional distress on the saturday to make him happy. He promised me a lot of things and he broke most of them so I cannot move on or trust anyone else. and I cannot let go as I told him I will wait for him if I have to… how do I convince him to listen to me and understand… make him realise he does care?! Sorry its long but I really cannot make life hard for others as he is the only one I could give everything to. I love him. and I cannot live without him and I know its stupid I keep asking myself why im bothering but I just love him… I dont know how else to exlain it… just please help =( x
