a breakup

I just broke up with my girlfriend today and I'm kind of a wreck. I think it was the right choice because we were long-distance and the lack of communication was putting a huge strain on us. She had also done things towards the beginning of our relationship that hurt me, but that I put aside because I was afraid of seeming too emotional. When I brought them up and asked her to explain why she did what she did, she basically said, "I guess I'm sorry is what I should say right now." I don't know... I deserve better than someone who can't make time to at least let me know that she wouldn't be able to talk to me much for a few days instead of just ignoring me. I deserve someone who gives me an actual apology or explanation when I tell them they've hurt me. Still, I'm incredibly sad... any tips for getting over a break up?
