My best friend, and boyfriend breaking it off

So, me and my boyfriend had a relationship for over 2 years. Things were excellent when we started going out, it was like we had finally found eachother. Before him, guys weren't an option. I had too many cheating and just mean problems before him with guys. Well, anyhow, the point is I really love him, but he abrupty broke up with me about.. 3 days ago. For the past 3 days I've been in hell because, he never gave me a true reason. He was hiding something, but I know he wasn't cheating on me. We have talked since then, and man, it is hard to get things out of him, he doesn't like to open up. Well, he wants to take a break he says things aren't officially over completely yet. He showed me his journal, saying "I never wanted to show you this, but maybe it will clear things up" and it had all this stuff about me pissing him off and just him irritated at me. I'm thinkin, is that IT? Why hadn't he talked to me? I wrote him a long e-mail, (this is the communication method we've had for the last 3 days) about how I figured out the problem. I believe that we need to talk about our problems, because...am I not right when I say in relationships, there is no perfect one? People need to work things out and talk about issues. We never did this! I really want to give it another try, and I hope after our break he realizes it too. Someone, please just..give me something, some kind of advice to get me through this hell. He was my best friend, truly. I have no one now. I'm totally alone in this prison of heartbreak. Tweet
