I can honestly say that I can relate to what you are going through. My boyfriend just broke up with me for the same exact reason. How long ago did you all break up? If it is recent, then you should give him some time. I know this is like the worst because it's like a war with yourself to not pick up that phone. However, you need to know the truth. Did he break up with you out of anger or was it for real? Many times we say things that we really don't mean when we're angry that we wouldn't have said otherwise. When he cools off, he'll be able to think more clearly. And if he really doesn't want to be with you, then you'll know. Time right now is probablly the hardest thing to give him, but you want what's in his heart, not a decision made while he was pissed off.
