Boyfriend and i get in clueless fights over nothing, should i be worried the relationship is over?

Last night we got into a fight over i dont even remember. But it couldnt have been important or i would have remembered. I tried to call him during my lunch and couldnt bring myself to do it. Usually he calls me around 4 when he gets home from work and its now 5, still no call. Some days he even calls from work. Its our two month anniversary and we havent talked, or seen each other. Weve done this before but usually he calls a million times to say sorry. I cant bring myself to call him. We dont usually even fight over anything just fight because. I dont know why. But we keep doing it. Last night it was the worse, when he left he threw something at me, nothing big or hard, just like a foam dart my brother was playing with but we were like a foot away and then slammed the door on his way out. He sped out of the driveway so fast i thought he was going to hit the tree in my yard. Im so upset about this but i cant call him. I really love him and wish we would stop doing this. I am willing to work it out, whatever we have a problem with. UGH! Should i be worried the relationship is over?
