I, too, am dealing with a recent breakup, and I can relate to having physical pain. I have a tendency to focus in on tiny little things that remind me of him and replay them over and over. When I do this, I can feel my heart quicken and everything starts to hurt. I think it’s important to to take some nice deep breaths and maybe a short walk if possible. I’ve also had some luck with visualizing letting my thoughts go (sending them up in little balloons is what works for me).

I’m sorry he’s behaving in such a way in a public fashion, but I don’t think you should take that as a reflection on your relationship. Most importantly you know what you felt, and you shouldn’t worry about how he feels now. I think it’s useful to focus on yourself. If it’s any consoloation at all, I know what you’re going through. It hurts when our daily life changes so radically and our plans for the future are taken away. I’m happy to hear you are making new plans. Today a friend said to me “things have a way of picking up,” and I think he’s right. Hang in there.
