h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Been with my boyfriend for bout 4 months and we both love each other and he have been arguing recently, but when i finished work for Xmas we got on so well cause we got to see each other everyday. But last Saturday we had an arguement as he said he was goning to phone me at 8:30 to tel me hes on his way round, it then came too 9:30 and i wondered where he was, so i phoned him and he was out with his mates saying he couldnt come round. I got stressed and put the fone down and told him to stuff the relationship up his arse, but only said it cause i was pissed off. Since then he hasnt wanted to speak to, say i piss him off, we have finished again, i said i was sorry and dint mean it but he doesnt listen. What can i do to make him see i didnt mean it. He said he doesnt know if he wants to get back with me either, i have tryed foning and hes really horriasble to me on the fone. Im scared this is the end for good, but i dont want it too be..what can i do to get him back? im so upset iv cryed myself to sleep every night since last sunday,
