Breaking up is hard to do

I never knew how hard breaking up, or semi-breaking up, really was. I'd never been through a breakup before, but now my serious relationship may be ending and I feel like my heart has just been torn in half. It's such a terrible situation and now I don't know how I can ever move on and love someone again. I never understood how people could say they never wanted to be in another relationship after a breakup, but now I understand why. I can only hope that this will somehow make me stronger and teach me something. Something good has to come out of it.
